The Philips CT Big Bore is a Computed Tomography X-Ray System intended to produce images of the head and body by computer reconstruction of x-ray transmission data taken at different angles and planes. These devices may include signal analysis and display equipment, patient and equipments and accessories. These systems are indicated for head and whole body X-ray Computed Tomography applications in oncology, vascular and cardiology, for patients of all ages.
These scanners are intended to be used for diagnostic imaging and for low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer*. The screening must be performed within the established inclusion criteria of programs / protocols that have been approved and published by either a governmental body or professional medical society.
- Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
The Philips CT Big Bore is currently available in two system configurations, the Oncology configuration and the Radiology (Base) configuration.
The main components (detection system, the reconstruction algorithm, and the x-ray system) that are used in the Philips CT Big Bore have the same fundamental design characteristics and are based on comparable technologies as the predicate.
The main system modules and functionalities are:
- Gantry. The Gantry consists of 4 main internal units:
a. Stator a fixed mechanical frame that carries HW and SW
b. Rotor A rotating circular stiff frame that is mounted in and supported by the stator.
c. X-Ray Tube (XRT) and Generator, fixed to the Rotor frame
d. Data Measurement System (DMS) a detector array, fixed to the Rotor frame - Patient Support (Couch) carries the patient in and out through the Gantry bore synchronized with the scan
- Console A two part subsystem containing a Host computer and display that is the primary user interface and the Common Image Reconstruction System (CIRS) - a dedicated, powerful image reconstruction computer
In addition to the above components and the software operating them, each system includes workstation hardware and software for data acquisition, display, manipulation, storage and filming as well as post-processing into views other than the original axial images. Patient supports (positioning aids) are used to position the patient.
This document describes the Philips CT Big Bore, a Computed Tomography X-Ray System. The submission focuses on demonstrating substantial equivalence to a predicate device rather than a standalone clinical efficacy study with acceptance criteria in the typical sense of a diagnostic AI product. Therefore, much of the requested information regarding clinical studies and expert review for ground truth is not directly applicable in the same way.
However, based on the provided text, we can infer and extract the following:

2. Sample Size for Test Set and Data Provenance
The document does not explicitly state a "test set" in the context of an AI/algorithm-driven diagnostic study. Instead, it refers to "bench testing included basic CT performance tests on phantoms" and "Sample clinical images were provided with this submission, which were reviewed and evaluated by radiologists."
- Sample Size for Test Set: Not specified for clinical images. For bench testing, it refers to "phantoms."
- Data Provenance: Not specified for the "sample clinical images." Given the context of a 510(k) for a hardware device, it's highly likely these were internal and possibly from a variety of sources. It's not stated whether they were retrospective or prospective.
3. Number of Experts and Qualifications for Ground Truth
- Number of Experts: "radiologists" (plural, but exact number not specified).
- Qualifications of Experts: Only "radiologists" are mentioned. No details on years of experience or subspecialty.
4. Adjudication Method for Test Set
- Adjudication Method: Not specified. The document states, "All images were evaluated to have good image quality," suggesting a qualitative assessment rather than a structured adjudication process for a specific diagnostic task.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
- MRMC Study: No, a typical MRMC comparative effectiveness study was not performed as described. This submission is for a CT scanner itself, not an AI-assisted interpretation tool where human readers' performance with and without AI would be compared.
- Effect Size of Human Readers with AI vs. without AI: Not applicable, as this was not an AI-assistance study.
6. Standalone (Algorithm Only) Performance Study
- Standalone Study: No, this was not a standalone algorithm performance study. The submission is for a complete CT imaging system. The performance metrics reported are for the overall system, not an isolated algorithm. The document mentions "optional software algorithm called WARP or DAS" for increasing slice count, and features like "iDose4" (an extension of DoseRight) and "FDOM, 3D-DOM" for dose modulation, but their standalone performance is not detailed in terms of a clinical study.
7. Type of Ground Truth Used
- Type of Ground Truth: For the "sample clinical images," the ground truth seems to be expert opinion / qualitative assessment by radiologists that the image quality was "good." For the technical performance parameters (MTF, CTDIvol, CT number accuracy, Noise, Slice Thickness), the ground truth was derived from physical phantom measurements against established technical specifications.
8. Sample Size for the Training Set
- Sample Size for Training Set: Not applicable. This document describes a CT scanner (hardware and embedded software), not a machine learning model that would have a separate "training set" in the conventional sense. The "training" for the system's development would be through engineering design, iterative testing, and adherence to established physical and software engineering principles.
9. How Ground Truth for the Training Set Was Established
- How Ground Truth for Training Set Was Established: Not applicable. (See point 8). The development of the CT system likely involved extensive engineering design, simulations, and validation against known physical principles and performance targets, which are fundamentally different from establishing ground truth for a machine learning training set.

Philips Medical Systems (Cleveland) Inc.
This device is a diagnostic imaging system for that combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT) systems. The CT subsystem produces cross-sectional images of the body by computer reconstruction of x-ray transmission data. The PET subsystem produces images of the distribution of PET radiopharmaceuticals in the patient body (specific radiopharmaceuticals are used for whole body, brain, heart and other organ imaging). CT data is applied to the PET data for attenuation correction. The PET subsystem also provides for list mode, dynamic, and gated acquisitions. This system is intended for patients of all ages.
Image processing and display workstations provide software applications to process, analyze, display, quantify and interpret medical images/data.
The PET and CT images may be registered and displayed in a "fused" (overlaid in the same spatial orientation) format to provide combined metabolic and anatomical data at different angles. Trained professionals use the images in:
· The evaluation, detection and diagnosis of lesions, disease and organ function such as but not limited to cancer, cardiovascular disease, and neurological disorders.
· The detection, localization, and staging of tumors and diagnosing cancer patients.
· Radiation therapy treatment planning and interventional radiology procedures.
The system includes software that provides a quantified analysis of regional cerebral activity from PET images.
Cardiac imaging software provides functionality for the quantification of cardiology images and data sets including but not limited to myocardial perfusion for the display of wall motion and quantification of left-ventricular function parameters from gated myocardial perfusion studies and for the 3D alignment of coronary artery images from CT coronary angiography onto the myocardium.
Both subsystems (PET and CT) can also be operated independently as fully functional, diagnostic imaging systems including application of the CT scanner as a radiation therapy simulation scanner.
This scanner is also intended to be used for diagnostic imaging and for low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer*. The screening must be performed within the established inclusion criteria of programs / protocols that have been approved and published by either a governmental body or professional medical society.
- Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
The proposed Ingenuity TF is an integrated diagnostic imaging system that combines Positron Emission Tomography (PET) and X-ray Computed Tomography (CT). PET uses radiopharmaceuticals to obtain images by measuring the internal distribution of radioactivity within head, body and total body. PET technology enables the practitioner to reconstruct high-resolution, three-dimensional images of biochemical and metabolic processes of organs within the body. The Ingenuity TF utilized Time-of-Flight (ToF) technology for the PET reconstruction. CT is a medical imaging technique that uses Xrays to obtain cross-sectional images of the head or body. The system utilizes the CT technology to obtain anatomic images of the human body and PET technology to obtain functional images of the human body. The CT component can be utilized by clinicians for lung cancer screening. As such, lung cancer screening has been added to the Ingenuity TF intended use. The integration of the anatomical data from CT with the metabolic data from PET gives clinicians the visual information necessary to define the severity, as well as the extent, of the disease. The major subsystems of the PET/CT include the PET image reconstruction subsystem, the PET Data Acquisition subsystem, the CT Image reconstruction subsystem, the CT acquisition subsystem, the PET Gantry, the CT Gantry and the patient table. The system is suitable for all patients, infant through adult.
Here's a summary of the acceptance criteria and study information for the Ingenuity TF device based on the provided text, focusing on what is and isn't available for each point:
1. Table of Acceptance Criteria and Reported Device Performance
The provided FDA 510(k) summary does not include a direct table of specific acceptance criteria (performance metrics with pass/fail thresholds) and corresponding reported performance for the Ingenuity TF. Instead, it states that:
- Acceptance Criteria (Implicit): The device was designed to meet "established design input requirements," "user needs and intended use," and comply with "FDA recognized consensus standards."
- Reported Performance (General): Design Verification activities "demonstrate the Ingenuity TF meets the established design input requirements." "Design Validation of user needs and intended use was conducted via simulated use testing." "Traceability from requirements to test plans to test results confirmed... that design requirements were met."
The document focuses on demonstrating substantial equivalence to a predicate device rather than providing quantitative performance against specific acceptance criteria for standalone performance.
2. Sample Size Used for the Test Set and Data Provenance
This information is not provided in the document. The text mentions "simulated use testing" and "clinical workflow validation," but does not specify the sample size of cases or the provenance (country, retrospective/prospective) of any test data.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
This information is not provided. If an expert panel was used for simulated use testing or clinical workflow validation, their number and qualifications are not detailed.
4. Adjudication Method for the Test Set
This information is not provided.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
A multi-reader multi-case (MRMC) comparative effectiveness study was not conducted for the Ingenuity TF. The document explicitly states: "The Ingenuity TF did not require clinical study since substantial equivalence to the primary currently marketed and predicate device was demonstrated with the following attributes: Intended Use; Technological characteristics; Non-clinical performance testing; and Safety and effectiveness." Therefore, an effect size of human readers' improvement with AI vs. without AI assistance is not reported.
6. Standalone Performance Study
A standalone performance study (i.e., algorithm only without human-in-the-loop performance) was not explicitly detailed as a separate clinical study. The device itself is a diagnostic imaging system (a PET/CT scanner), not an AI algorithm intended for standalone interpretation. Performance was assessed through non-clinical testing and comparison to a predicate device. The "Image Quality verification" mentioned under non-clinical testing would involve evaluating the image output itself, which is a form of standalone evaluation of the device's output quality.
7. Type of Ground Truth Used
For the non-clinical and simulated use testing mentioned, the type of "ground truth" would likely involve:
- Established Design Input Requirements: Compliance with specified technical and functional requirements.
- User Needs and Intended Use: Verified through simulated use.
- Consensus Standards: Compliance with international safety and performance standards (e.g., NEMA NU 2:2012 for PET performance, IEC 60601 series).
For any "Image Quality verification," ground truth might be derived from phantom studies with known properties or comparison against highly detailed reference images, but this is not explicitly stated. The document doesn't mention pathology, expert consensus on clinical cases, or outcomes data as direct ground truth for device acceptance.
8. Sample Size for the Training Set
The document does not mention a training set sample size. This device is a PET/CT scanner, not an AI model that undergoes a typical training phase with a dedicated dataset. While it incorporates "software that provides a quantified analysis," the development of this software (its training, if any, for specific analytical tasks) is not detailed.
9. How the Ground Truth for the Training Set Was Established
Since there is no mention of a training set for the device itself (as it's a hardware imaging system with integrated software), the method for establishing ground truth for a training set is not applicable/not provided.

These devices may include signal analysis and display equipment, patient and equipments and accessories. The iCT is indicated for head, whole body, cardiac and vascular X-ray Computed Tomography applications in patients of all ages.
These scanners are intended to be used for diagnostic imaging and for low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer*. The screening must be performed within the established inclusion criteria of programs / protocols that have been approved and published by either a governmental body or professional medical society.
*Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
The Philips iCT is currently available in two system configurations, iCT and iCT SP. Identical to the predicate, the Philips iCT CT System produces cross-sectional images of the body head and body by computer reconstruction of x-ray transmission data taken at different angles and planes. The main components (detection system, the reconstruction algorithm, and the x-ray system) that are used in the Philips iCT have the same fundamental design characteristics and are based on comparable technologies as the predicate.
The main system modules and functionalities are:
- Gantry. The Gantry has an aperture of 700mm and consists of the following internal units:
a. Stator a fixed mechanical frame that carries hardware and software.
b. Rotor A rotating circular stiff frame that is mounted in and supported by the stator.
c. X-Ray Tube (XRT) and Generator fixed to the Rotor frame. The generator has a power rating of 100kW with optional 120kW.

- Software features to view and analyze images.
This document is a 510(k) premarket notification for the Philips iCT CT System, which is a Computed Tomography X-Ray System. The document details the device's indications for use, description, and a comparison with a predicate device (Philips Brilliance Volume) to establish substantial equivalence.
Based on the provided text, the Philips iCT CT System is a Computed Tomography (CT) X-Ray System. The document outlines that the system is intended to produce images of the head and body by computer reconstruction of x-ray transmission data. It also explicitly states its indication for "low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer."
Regarding acceptance criteria and the study proving the device meets these criteria:
The document focuses on demonstrating substantial equivalence to a predicate device (Philips Brilliance Volume) rather than presenting a performance study with explicit acceptance criteria for a novel AI/ML-driven diagnostic device. This means the 510(k) submission primarily relies on comparing the design, technology, and specified performance parameters of the new device to an already legally marketed device, and showing that any differences do not raise new questions of safety or effectiveness.
Therefore, many of the requested elements for an AI/ML diagnostic device study (like sample size for test sets, expert adjudication, MRMC studies, standalone performance with specific metrics like sensitivity/specificity, or ground truth establishment for novel findings) are not detailed or applicable in the traditional sense for this 510(k) submission. This submission is for hardware (CT scanner) with associated software for image reconstruction, not primarily a sophisticated AI/ML diagnostic algorithm operating on those images for making clinical decisions beyond image acquisition and display.
Here's an attempt to address the requested information based on the provided document:
1. Table of acceptance criteria and the reported device performance:
Since this is a 510(k) for a CT system demonstrating substantial equivalence, the "acceptance criteria" are implicitly met by showing that the proposed device's characteristics are either identical to or comparable to the predicate device, and any changes do not adversely affect safety or effectiveness. The document presents a comparative table, not a table of specific numerical performance acceptance criteria for a diagnostic algorithm.

2. Sample size used for the test set and the data provenance:
The document mentions "Design Verification planning and testing was conducted at the sub-system and at the system level." It also states "Design validation of user needs and intended use was conducted via simulated use testing with production equivalent Philips iCT CT Systems."
- Test Set Sample Size: Not specified in terms of patient data or clinical cases for diagnostic performance. The document refers to "system and sub-system level verification" and "simulated use testing." This suggests engineering and functional testing rather than a large-scale clinical performance study on a specific number of patient scans.
- Data Provenance: Not specified. Given it's a Philips product for a global market, the data provenance for engineering/simulated testing is likely internal R&D, not necessarily specific patient data sets from particular countries. "Retrospective or prospective" is not applicable in the context of hardware/software functional testing described.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
Not applicable. This 510(k) is not for an AI/ML diagnostic algorithm that requires expert-established ground truth on clinical images for its performance evaluation. The "ground truth" for a CT system's performance in this context would be its physical specifications, image quality metrics (like spatial resolution, contrast resolution, noise), and safety parameters (radiation dose). These are typically verified against engineering specifications, phantoms, and regulatory standards, not clinical ground truth established by experts.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
Not applicable. No clinical image or diagnostic performance adjudication is described.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
Not applicable. This submission is for a CT hardware system, not an AI-assisted diagnostic tool that integrates with human readers. The "low dose CT lung cancer screening" indication refers to the capability of the scanner, and refers to existing clinical literature (National Lung Screening Trial) as evidence for the efficacy of low-dose CT screening in general, not specific AI augmentation.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
Not applicable for a diagnostic algorithm. The device, the Philips iCT CT System, is the standalone imaging system for image acquisition and reconstruction. Its performance is evaluated against engineering specifications and industry standards.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
The "ground truth" for the device's technical performance (e.g., image quality, scan range, rotation times) would be established by:
- Engineering specifications: The designed parameters of the CT system components.
- Physical phantoms: Standardized objects used to measure image quality characteristics (e.g., spatial resolution, contrast-to-noise ratio, slice thickness accuracy).
- Calibration procedures: Ensuring the system's measurements are accurate.
- Compliance with international standards: (e.g., IEC 60601 series for medical electrical equipment safety and performance).
For the lung cancer screening indication, the document refers to "clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature." This means the ground truth for the clinical utility of low-dose CT screening, in general, is based on outcomes data from large clinical trials. The device's "acceptance" for this indication is based on its capability to perform scans at low dose within established protocols, implying it meets the technical requirements to participate in such screening programs.
8. The sample size for the training set:
Not applicable. This is not for a machine learning model that requires a "training set" of clinical data in the typical sense.
9. How the ground truth for the training set was established:
Not applicable. No machine learning training set is described.
In summary: This 510(k) document is a regulatory submission for a general-purpose CT scanner. Its "acceptance criteria" and "proof" primarily revolve around demonstrating that its technical specifications, design, and functionality are substantially equivalent to a previously cleared predicate device, and that any modifications (like extended scan range, increased slices, or removal of gantry tilt) do not compromise safety or effectiveness. The inclusion of "low dose CT lung cancer screening" as an indication relies on the device's ability to perform scans compatible with established clinical guidelines, rather than presenting novel AI performance data for nodule detection or characterization.

The IQon Spectral CT is a Computed Tomography X-Ray System intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data taken at different angles and planes. This device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories. The IQon Spectral CT system acquires one CT dataset - composed of data from a higher-energy detected x-ray spectrum and a lower- energy detected x-ray spectra may be used to analyze the differences in the energy dependence of the attenuation coefficient of different materials. This allows for the generation of images at energies selected from the available spectrum and to provide information about the chemical composition of the body materials and/or contrast agents. Additionally, materials analysis provides for the quantification and graphical display of attenuation, material density, and effective atomic number.
This information may be used by a trained healthcare professional as a diagnostic tool for the visualization and analysis of anatomical and pathological structures.
The system is also intended to be used for low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer*.
The screening must be performed within the established inclusion criteria of programs / protocols that have been approved and published by either a governmental body or professional medical society.
*Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
The IQon Spectral CT is a whole-body computed tomography (CT) X-Ray System featuring a continuously rotating x-ray tube and detectors gantry and multi-slice capability. The acquired xray transmission data is reconstructed by computer into crosssectional images of the body taken at different angles and planes. This device also includes signal analysis and display equipment; patient and equipment supports; components; and accessories. The IQon Spectral CT includes the detector array previously described in K133674 "Philips IQon Spectral CT".
The IQon Spectral CT consists of three main components - a scanner system that includes a rotating gantry, a movable patient couch, and an operator console for control and image reconstruction; a Spectral Reconstruction System; and a Spectral CT Viewer. On the gantry, the main active components are the x-ray high voltage (HV) power supply, the x-ray tube, and the detection system.
In addition to the above components and the software operating them, the system includes workstation hardware and software for data acquisition; and image display, manipulation, storage, and filming, as well as post-processing into views other than the original axial images. Patient supports (positioning aids) are used to position the patient.
This document, a 510(k) Pre-Market Notification for the Philips IQon Spectral CT (K163711), indicates that no new clinical study was required to demonstrate substantial equivalence for the core device to its predicate (K133674). The addition of "Low Dose CT Lung Cancer Screening" to the Indications for Use was supported by a comparative assessment to another cleared device (K153444), rather than a de novo clinical study for the IQon Spectral CT itself.
Therefore, much of the requested information about acceptance criteria for a specific study conducted for this device, sample sizes for test sets, ground truth establishment, expert qualifications, and MRMC studies, is not present in this document as it pertains to this specific 510(k) submission for the IQon Spectral CT. The document relies heavily on the substantial equivalence to previously cleared devices.
However, I can extract information related to the general acceptance of the device based on non-clinical testing and its reliance on previously cleared predicate devices.

Study Details (as inferable from the document):
-
Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- This 510(k) relies on non-clinical verification and validation testing, and comparative assessment to predicate devices, rather than a new clinical study. Therefore, there is no "test set" in the context of a new prospective or retrospective clinical study of patients, or information on data provenance, within this specific submission. The non-clinical tests would have involved phantom or laboratory testing.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
- Not applicable, as no new clinical test set requiring expert ground truth establishment is described in this 510(k). The "ground truth" for compliance testing would be defined by the standards and technical specifications being verified.
-
Adjudication method (e.g. 2+1, 3+1, none) for the test set:
- Not applicable, as no new clinical test set is described.
-
If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:
- No MRMC study is mentioned or appears to have been conducted for this 510(k) submission. The device is a CT scanner, not an AI-assisted diagnostic tool in the typical sense that would necessitate an MRMC study for improved reader performance for this submission. The "minor improvements to some spectral algorithms" are internal technical refinements, not standalone AI algorithms for interpretation.
-
If a standalone (i.e. algorithm only without human-in-the loop performance) was done:
- Not applicable. The IQon Spectral CT is a medical imaging device. Its function involves acquiring and processing images for interpretation by a human healthcare professional. There isn't a standalone algorithm performance evaluation described independent of the imaging system. The modifications mentioned ("minor improvements to some spectral algorithms") are part of the image generation/processing pipeline, not a separate diagnostic algorithm.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc):
- For the non-clinical performance data, the ground truth would be the established specifications and requirements defined by the international and FDA-recognized consensus standards (e.g., image quality metrics, dose measurements in phantoms, electrical safety parameters) and the technical design requirements of the device.
- For the Low Dose CT Lung Cancer Screening indication, the ground for clinical validity would stem from the clinical literature referenced (e.g., National Lung Screening Trial) and the established inclusion criteria/protocols of governmental/professional medical societies, which inherently rely on outcomes data and pathology for nodule malignancy. The IQon Spectral CT's role is to provide the imaging data.
-
The sample size for the training set:
- Not applicable. This document describes a medical device clearance based on substantial equivalence and non-clinical testing, not a machine learning model requiring a training set. The "spectral algorithms" receiving "minor improvements" are likely image reconstruction and processing algorithms that have been refined based on engineering principles and potentially internal validation, not AI models trained on large datasets.
-
How the ground truth for the training set was established:
- Not applicable, as no training set for a machine learning model is described in this 510(k) submission.

The provide text is a 510(k) premarket notification for the Philips Medical Systems (Cleveland), Inc. Pinnacle3® Radiation Therapy Planning System. This document focuses on demonstrating substantial equivalence to a predicate device and does not contain detailed information about the acceptance criteria and study proving device performance as typically understood for AI/ML devices.
Here's an analysis based on the information provided, highlighting what is present and what is not present:
Key Takeaways from the Document:
- Device Type: This is a Radiation Therapy Planning System, a software package. It's not explicitly an AI/ML device in the sense of making diagnostic predictions or interpretations, although some features (like Auto-segmentation, Deformable Image Registration) could potentially leverage AI/ML techniques. The document describes it as "software" and emphasizes "physics modeling," "dose computation," and "optimization processes."
- Focus on Substantial Equivalence: The primary goal of this 510(k) is to demonstrate that the updated Pinnacle3® RTP System (Version 16.0) is substantially equivalent to its predicate device (K130992). This pathway typically relies on comparing new features to existing, approved functionalities rather than extensive novel clinical effectiveness studies.
- Verification Testing, Not Clinical Trials: The document explicitly states: "Clinical trials were not performed as part of the development of this product. Clinical testing on patients is not advantageous in demonstrating substantial equivalence or safety and effectiveness of the device since testing can be performed such that no human subjects are exposed to risk. Verification testing was performed as required per the risk analyses and demonstrated that no new risks were introduced with the modifications in this submission." This strongly indicates that the "study" proving the device meets acceptance criteria involved non-clinical verification testing rather than a traditional performance study with a test set, ground truth, and human experts.
- Acceptance Criteria Mentioned but Details Lacking: The document states that "The results of these tests demonstrate that the Pinnacle3® RTP System met the acceptance criteria and is adequate for its intended use." However, what those specific acceptance criteria were (e.g., specific quantitative thresholds for dose calculation accuracy, registration accuracy, etc.) and the detailed results are not described in this summary.
Given the document's nature as a 510(k) summary focused on substantial equivalence and non-clinical verification, many of the requested items (especially those related to clinical performance studies, expert consensus, sample sizes for test/training sets, and AI-specific metrics) are not present or applicable in the provided text.
Here's how to fill out your requested table and information, with many entries indicating "Not Applicable" or "Not Provided" based on the document:
1. Table of Acceptance Criteria and Reported Device Performance
Acceptance Criteria Category | Specific Acceptance Criteria (Not Provided in Detail) | Reported Device Performance (Summary from Text) |
---|---|---|
System Functionality | Not explicitly detailed (e.g., "dose calculation accuracy within X%"). | "Software verification testing has demonstrated that the IMPT and DIR features of the Pinnacle3® RTP System performs as intended in the specified use." |
Risk Mitigation | All identified risks are sufficiently mitigated. | "The risk management activities show that all risks are sufficiently mitigated and that the overall residual risk is acceptable." |
Safety & Effectiveness | No new concerns regarding safety or effectiveness. | "No new concerns regarding safety or effectiveness have been raised by the introduction of the additional features." |
Compliance with Standards | Compliance with IEC 62304 and ISO 14971. | "The Pinnacle® RTP System complies with the following international and FDA-recognized consensus standards: IEC 62304, ISO 14971." |
Intended Use | Adequate for its intended use. | "The results of these tests demonstrate that the Pinnacle3® RTP System met the acceptance criteria and is adequate for its intended use." |
2. Sample size used for the test set and the data provenance
- Sample Size: Not provided. The verification testing likely used various defined test cases or phantoms rather than a "test set" of patient data in the typical sense of a clinical performance study for an AI device.
- Data Provenance: Not applicable/not provided for patient data. The development and verification likely used simulated or phantom data, or possibly a limited set of de-identified patient data for specific test cases.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not provided.
- Qualifications of Experts: Not provided.
- Note: Since this was primarily verification testing of a planning system rather than a diagnostic AI device, the "ground truth" would likely be established by engineering specifications, known physical properties (e.g., for dose calculations in phantoms), or clinical standards, rather than direct expert annotation of medical images for a test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Adjudication Method: Not applicable/none. The document describes "verification testing" against specified requirements and risk analyses, not a human reader study requiring adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Study: No. The document explicitly states "Clinical trials were not performed." This type of study is typically done for AI-assisted diagnostic devices.
- Effect Size: Not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone Performance: While the system calculates and optimizes plans, the performance study described is non-clinical verification testing of the software's adherence to specifications and risk mitigation. The device is intended to "assist the clinician," and plans "are to be evaluated, modified and implemented by qualified medical personnel," indicating it's not a standalone diagnostic device but a tool for medical professionals. The verification testing itself would be "standalone" in the sense that the software's outputs were checked against expected results as part of the engineering validation.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Type of Ground Truth: Not explicitly stated but inferred from "verification testing" and "risk analyses." Likely involved:
- Engineering Specifications: Outputs (e.g., calculated dose, image registration accuracy) compared against predefined numerical tolerances.
- Physics Models: Accuracy of dose calculations verified against established radiation physics models and experimental data from phantoms.
- Clinical Standards: Verification that the system generates plans that align with accepted clinical practices and safety parameters for radiation therapy.
8. The sample size for the training set
- Sample Size for Training Set: Not applicable/not provided. This is a software planning system with physics models and optimization algorithms, not a machine learning model that relies on a "training set" in the conventional sense for image classification or prediction tasks. While some features like "Atlas Auto-Segmentation" or "Model-Based Segmentation" might involve pre-trained models, the document does not provide details on their training data.
9. How the ground truth for the training set was established
- How Ground Truth was Established: Not applicable/not provided for a training set in the AI/ML context. If certain sub-features (e.g., auto-segmentation) use models, the method for establishing their "ground truth" for training is not disclosed in this document.

*Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011: 365:395-409) and subsequent literature, for further information,
The Philips Ingenuity CT consists of three system configurations, the Philips Ingenuity CT, the Philips Ingenuity Core and the Philips Ingenuity Core128. These systems are Computed Tomography X-Ray Systems intended to produce cross-sectional images of the body by computer reconstruction of X-ray transmission data taken at different angles and planes. These devices may include signal analysis and display equipment, patient, and equipment supports, components and accessories. These scanners are intended to be used for diagnostic imaging and for low dose CT lung cancer screening for the early detection of Jung nodules that may represent cancer*.

Here's an analysis of the acceptance criteria and the study proving the device meets them, based on the provided text:
Important Note: The provided document is a 510(k) submission for a CT scanner (Philips Ingenuity CT), which focuses on demonstrating substantial equivalence to a predicate device (Philips Plus CT Scanner), rather than establishing new performance claims with specific acceptance criteria and clinical trial results typical for entirely novel AI/ML devices. Therefore, much of the requested information, particularly regarding AI-specific performance (like effect size of human reader improvement with AI, standalone AI performance, ground truth for training AI models) is not directly present. The clinical evaluation described is a comparative image quality assessment rather than a diagnostic accuracy clinical trial.
1. Table of Acceptance Criteria and Reported Device Performance
Given the nature of this 510(k) submission, the "acceptance criteria" are primarily established against international and FDA-recognized consensus standards for medical electrical equipment and CT systems, and against the performance of the predicate device. The "reported device performance" refers to the successful verification against these standards and equivalence to the predicate.
Acceptance Criteria Category | Specific Criteria / Standard Met | Reported Device Performance |
---|---|---|
Safety and Essential Performance (General) | IEC 60601-1:2006 (Medical electrical equipment Part 1: General requirements for basic safety and essential performance) | All verification tests were executed and passed the specified requirements. |
Electromagnetic Compatibility (EMC) | IEC 60601-1-2:2007 (Medical electrical equipment Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances -Requirements and tests) | All verification tests were executed and passed the specified requirements. |

Safety of X-ray Equipment (Specific) | IEC 60601-2-44:2009 (Medical electrical equipment Part 2-44: Particular requirements for the safety of X-ray equipment) | All verification tests were executed and passed the specified requirements. |
Software Life Cycle Processes | IEC 62304:2006 (Medical device software Software life cycle processes) | Software Documentation for a Moderate Level of Concern (per FDA guidance) was included. All verification tests were executed and passed the specified requirements. |
Risk Management | ISO 14971 (Medical devices Application of risk management to medical devices (Ed. 2.0, 2007)) | Traceability between requirements, hazard mitigations and test protocols described. Test results per requirement and per hazard mitigation show successful mitigation. |
Image Quality Metrics (Comparative to Predicate) | CT number accuracy and uniformity, MTF, noise reduction performance (i.e., iDose4 vs. FBP), slice thickness, slice sensitivity profiles. Diagnostic image quality for brain, chest, abdomen, pelvis/orthopedic. | Bench tests included patient support/gantry positioning repeatability and accuracy, laser alignment accuracy, CT image quality metrics testing. Sample phantom images provided. Clinical evaluation found no difference in image quality between iDose4 and FBP, with iDose4 scoring higher in most cases, maintaining diagnostic quality. |
Functional and Non-Functional Requirements (System Level) | System Requirements Specification, Subsystem Requirement Specifications, User Interface Verification | Functional and non-functional regression tests, as well as user interface verification, provided in the Traceability Matrix (successful). |

Manufacturing Validation | Covered requirements related to operations and manufacturing. | Validation test plan executed as planned, acceptance criteria met for each requirement. |
2. Sample Size Used for the Test Set and Data Provenance
The document does not specify a distinct "test set" sample size in the sense of a number of clinical cases or patient images used for a diagnostic accuracy study. Instead, it refers to:
- Bench tests: These involved phantom images and physical testing of the system (e.g., patient support/gantry positioning repeatability and accuracy, laser alignment accuracy, CT image quality metrics testing). No sample size for these is given.
- Clinical Evaluation: An "image evaluation" was performed involving "images of the brain, chest, abdomen and pelvis/peripheral orthopedic body areas." The number of images or patient cases used for this evaluation is not specified.
- Data Provenance: Not explicitly stated, but given it's a Philips product, it's likely internal development and validation data. There is no mention of external datasets or specific countries of origin. The evaluation compares FBP and iDose4 reconstructions of the same images. The clinical evaluation implicitly relates to retrospective data as it compares reconstructed images.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
- Number of Experts: "a qualified radiologist". So, one expert.
- Qualifications of Experts: Described only as "a qualified radiologist." No specific experience (e.g., years of experience, subspecialty) is provided.
4. Adjudication Method for the Test Set
The evaluation was performed by a single radiologist using a 5-point Likert scale. Therefore, no adjudication method (like 2+1, 3+1 consensus) was used as there was only one reviewer.
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was Done
No, an MRMC comparative effectiveness study was not done. The document describes an image evaluation by a single radiologist, not multiple readers. It also describes a comparison of image quality between reconstruction techniques (FBP vs. iDose4), not a comparison of human reader diagnostic performance with vs. without AI assistance.
- Effect size of human readers improving with AI vs without AI assistance: This information is not applicable as this type of study was not performed. The study evaluated if iDose4-reconstructed images (which is an iterative reconstruction technique for image quality improvement and dose reduction, not an AI for diagnosis) maintained diagnostic quality compared to standard FBP.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was Done
Yes, in spirit, the primary evaluation is about the algorithm's output quality. The iDose4 iterative reconstruction algorithm directly produces images without human intervention, and these images were then evaluated by a radiologist. The core of this 510(k) is about the technical performance and safety of the CT scanner and its components, including its reconstruction algorithms. The evaluation described ("image evaluation...") is a standalone assessment of the image quality produced by the iDose4 algorithm compared to standard FBP. It is not an "AI diagnostic algorithm" standalone performance, but rather an "image reconstruction algorithm" standalone performance.
7. The Type of Ground Truth Used
For the clinical image evaluation, the "ground truth" was established by the evaluation of a qualified radiologist using a 5-point Likert scale to determine if images were of "diagnostic quality" and for comparing image quality between reconstruction methods. This could be considered a form of "expert consensus," albeit from a single expert in this case. There is no mention of pathology or outcomes data being used as ground truth for this specific image quality assessment.
8. The Sample Size for the Training Set
Not applicable in the context of this 510(k) as presented.
The device (Philips Ingenuity CT) is a hardware CT scanner with associated software, including image reconstruction algorithms (like iDose4). While iterative reconstruction algorithms might involve some form of "training" or optimization during their development, the document does not speak to a "training set" in the sense of a dataset used to train a machine learning model for a specific diagnostic task that would typically be described in an AI/ML device submission. The description focuses on technical modifications and adherence to engineering and safety standards, and performance against a predicate device.
9. How the Ground Truth for the Training Set was Established
Not applicable for the reasons stated above (no "training set" for an AI/ML diagnostic model described).

The Philips Multislice CT Systems are Computed Tomography X-Ray Systems intended to produce cross-sectional images of the body by computer reconstruction of X-ray transmission data taken at different angles and planes. These devices may include signal analysis and display equipment supports, components and accessories. The scanners are intended to be used for diagnostic imaging and for low dose CT lung cancer screening for the early detection of lung nodules that may represent cancer*.
The screening must be performed within the established inclusion criteria of protocols that have been approved and published by either a governmental body or professional medical society.
*Please refer to clinical literature, including the results of the National Lung Screening Trial (N Engl J Med 2011; 365:395-409) and subsequent literature, for further information.
Philips Low Dose CT Lung Cancer Screening option can be used with Philips whole body multi-slice CT X-Ray Systems installed in a healthcare facility (clinic / hospital). These systems provide a continuously rotating X-ray tube and detector array with multi-slice capability. The acquired x-ray transmission data is reconstructed by computer into cross-sectional images of the body taken at different angles and planes. Reconstruction algorithms available are standard reconstruction (filtered back projection), iDose 4 and IMR iterative reconstruction. These systems also include signal analysis and display equipment, patient and equipment supports, components and accessories.
There are no functional, performance, feature, or design changes required for the qualified CT systems onto which the LDCT LCS Option is applied. Because none of the CTs will require hardware or software modifications, the Philips Low Dose CT Lung Cancer Screening option and the currently marketed and predicate Philips Multislice CT System for qualified CT systems in the installed base consists of:
- A set of up to three reference LDCT LCS protocols: standard reconstruction, standard reconstruction with iDose 4, and with IMR iterative reconstruction (where applicable), for each qualified CT System on a per CT platform basis;
- Detailed instructions on how to create the protocols on the corresponding CT System; and
- A dedicated Instructions for Use for LDCT LCS that covers all qualified systems.
This document is a 510(k) premarket notification for the Philips Multislice CT System with Low Dose CT Lung Cancer Screening. It primarily focuses on demonstrating substantial equivalence to existing predicate devices, rather than presenting a standalone study proving the device meats specific acceptance criteria in a clinical setting with human readers.
However, based on the provided text, I can infer the acceptance criteria relate to maintaining image quality parameters for Low Dose CT Lung Cancer Screening (LDCT LCS) that are equivalent to or better than standard CT performance, especially given the reduced radiation dose. The "study" proving this largely relies on non-clinical bench testing and references to external clinical literature and trials.
Here's a breakdown of the information you requested:
1. Table of Acceptance Criteria and Reported Device Performance
The document doesn't explicitly state "acceptance criteria" in a quantitative, measurable sense for a clinical study with patients. Instead, it focuses on demonstrating that the LDCT LCS option does not degrade image quality compared to existing CT systems and that existing clinical evidence supports the efficacy of LDCT LCS itself.
Here's a table based on the image quality parameters evaluated in non-clinical testing and the reported outcome of that testing:
Acceptance Criteria (Inferred from Image Quality Parameters Evaluated) | Reported Device Performance (Non-Clinical Bench Testing Outcomes) |
---|---|
Spatial Resolution (MTF): Ability to visualize fine anatomical details, preserved at lower dose. | "MTF is a measure of the high contrast spatial resolution performance of the system. Nodules in the lung are high contrast objects and therefore, MTF should be preserved at lower dose conditions." "Demontrates that the image quality metrics including MTF... are substantially equivalent among different family of scanners (Brilliance 16, Brilliance Big Bore, Brilliance 64/Ingenuity, Brilliance iCT and IQon)." |
Contrast Resolution (CNR): Ability to differentiate tissues with subtle differences in attenuation, sufficient for nodule detection. | "Sufficient Contrast-to-Noise is needed to detect solid and non-solid nodules in the lung. This parameter accounts for the contrast between an object and the background. This could also be a parameter that could influence nodule detectability." "The CNR scans were completed using the LDCT LCS scan protocols for all scanners in the comparison." "The results of non-clinical bench testing demonstrate that the image quality metrics including... Contrast to Noise Ratio are substantially equivalent among different family of scanners." "The contrast of the lung nodules it high relative to this increased noise, demonstrated by the CNR results (section 18) and NLST study." |
Image Noise (Standard Deviation): Acceptable background noise levels at reduced dose, not compromising nodule detectability/sizing. | "As dose is reduced, background noise in the image increases. If this noise becomes too large, nodule detectability and sizing measurement may be compromised." "The results of non-clinical bench testing demonstrate that the image quality metrics including... Image noise... are substantially equivalent among different family of scanners." "Noise goes up by the square root of the mAs. The contrast of the lung nodules it high relative to this increased noise, demonstrated by the CNR results (section 18) and NLST study." |
Noise Power Spectrum (NPS): Acceptable noise texture, not influencing nodule detection capabilities. | "Similar to the noise, changes in texture of the noise may have an influence on the nodule detection capabilities." "The NPS scans were completed using the LDCT LCS scan protocol." "The results of non-clinical bench testing also demonstrate the image quality parameters for iDose4 and IMR reconstructions are equivalent to, or better than standard FBP reconstruction." |
Slice Thickness: Accurate slice thickness for clear edges and boundaries of nodules. | "The ability to produce slice thicknesses (FWHM of the slice sensitivity profile) that are close to the nominal slice thickness is important in defining clear edges and boundaries of the nodule." "The results of non-clinical bench testing demonstrate that the image quality metrics including... Slice Thickness... are substantially equivalent among different family of scanners." |
CT Number Uniformity: Sufficient uniformity in the lung for robust nodule detectability. | "In a low dose scanning protocols such as with lung cancer screening, maintaining sufficient CT number uniformity throughout the lung and its various structures is important for more robust detectability of the nodules." "The results of non-clinical bench testing demonstrate that the image quality metrics including... CT number linearity, CT number accuracy... are substantially equivalent among different family of scanners." |
CT Number Linearity: Measured CT number in a nodule not significantly affected by low dose scanning. | "In a low dose scanning protocols such as with lung cancer screening, the CT number measured in a nodule may be affected and therefore measuring CT number linearity is important." "The results of non-clinical bench testing demonstrate that the image quality metrics including... CT number linearity... are substantially equivalent among different family of scanners." |
Image Artifacts: No new or increased artifacts obscuring anatomical details or mimicking pathology. | (Implicit in overall image quality assessment, not explicitly detailed as a separate quantified metric but mentioned as an important image quality parameter). "Image artifacts can obscure anatomical details and mimic pathology." |
Geometric Distortion: Accuracy of measurements and image correlation with other modalities. | (Implicit in overall image quality assessment, not explicitly detailed as a separate quantified metric but mentioned as an important image quality parameter). "Geometric distortion can affect the accuracy of measurements and the ability to correlate images with other modalities." |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Test Set Sample Size: Not applicable in the context of a clinical patient test set for this specific submission. The "test set" for demonstrating substantial equivalence related to image quality was composed of various CT scanner models and reconstruction algorithms.
- Data Provenance: The primary data used to support the efficacy of LDCT LCS itself comes from externally referenced clinical literature, specifically the National Lung Screening Trial (NLST) (N Engl J Med 2011; 365:395-409) and the International Early Lung Cancer Action Program (I-ELCAP), along with "subsequent literature." These were large-scale prospective clinical trials, likely conducted across multiple centers, including within the US (NLST).
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Number of Experts: Not applicable for this specific submission's non-clinical testing. The non-clinical image quality phantom measurements do not involve expert interpretation for ground truth.
- Qualifications of Experts: For the external clinical trials (NLST, I-ELCAP) referenced, radiologists and other medical professionals were involved in establishing diagnoses and outcomes, but their specific numbers and qualifications are not detailed in this 510(k) document.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Adjudication Method: Not applicable for this specific submission's non-clinical testing. No human adjudication was performed for the image quality metrics tested.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- MRMC Comparative Effectiveness Study: No, a multi-reader, multi-case comparative effectiveness study with human readers (with vs. without AI assistance) was not conducted or presented in this 510(k) submission. This submission is for the CT system itself with a low-dose protocol option, not for an AI-powered CAD (Computer-Aided Detection) or CADx (Computer-Aided Diagnosis) device. The device does not incorporate AI for interpretation.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Standalone Performance Study: No, a standalone algorithm-only performance study was not conducted or presented in this 510(k) submission. The device is a CT scanner, not an independent algorithm for diagnosis or detection.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Type of Ground Truth:
- For the image quality bench testing: Ground truth was established by the physical phantoms used for measurements (e.g., wire phantom for MTF, ramp/disk phantom for slice thickness, water/density phantoms for CT numbers).
- For the clinical efficacy of LDCT LCS (referenced externally): The ground truth for the NLST and I-ELCAP studies would have included pathology reports (for confirmed cancers), clinical follow-up/outcomes data (for stable or resolving nodules), and potentially expert consensus reviews of indeterminate findings.
8. The sample size for the training set
- Training Set Sample Size: Not applicable. This submission describes a CT scanner with a new protocol, not a machine learning algorithm that requires a training set. The reconstruction algorithms (iDose4, IMR) themselves would have been developed using various data, but details are not provided here.
9. How the ground truth for the training set was established
- Ground Truth for Training Set: Not applicable, as this is not an AI/ML device requiring a training set with ground truth established through labeled data in the context of this submission.

Pinnacle3 Radiation Therapy Planning System is a software package intended to provide planning support for the treatment of disease processes. Pinnacle3 Radiation Therapy Planning System incorporates a number of fully integrated subsystems, including Pinnacle3 Proton, which supports proton therapy planning. The full Pinnacle Radiation Therapy Planning System software package provides planning support for the treatment of disease processes, utilizing photon, proton, electron and brachytherapy techniques.
Pinnacle3 Radiation Therapy Planning System assists the clinician in formulating a treatment plan that maximizes the dose to the treatment volume while minimizing the dose to the surrounding normal tissues. The system is capable of operating in both the forward planning and inverse planning modes. Plans generated using this system is used in the determination of the course of a patient's radiation treatment. They are to be evaluated, modified and implemented by qualified medical personnel.
Pinnacle3® Radiation Therapy Planning System (hereafter Pinnacle3 RTP) provides radiation treatment planning for the treatment of benign or malignant diseases. When using Pinnacle " RTP, qualified medical personnel may generate, review, verify, approve, print and export the radiation therapy plan prior to patient treatment. Pinnacle RTP can provide plans for various radiation therapy modalities including, utilizing photon, proton, electron and brachytherapy techniques Stereotactic Radiosurgery, and Brachytherapy.
The Proton module builds on the Pinnacle Photon Treatment Planning Solution. A substantial part of the software architecture, display, connectivity and planning tools are transferable or extensible to the Proton Treatment Planning module. Using Pinnacle® RTP as the base-line architecture will address the needs of operating and future treatment centers to seamlessly integrate photon with proton treatment planning.
Pinnacle® RTP is a software package that runs on a Oracle Server and accessed through one or more clients, or an Oracle UNIX workstation and consists of a core software module (Pinnacle') and optional software features (the Proton module requires the Oracle server and cannot be run on a workstation). These optional software features, commonly referred to as "plug-ins", are typically distributed separate from the core software product (separate CD or DVD). The device has network capability to other Pinnacle® RTP workstations, thin client, and to both input and output devices via local area network (LAN) or wide area network (WAN).
Image data is imported from CT, MR, PET, PET-CT and SPECT devices using a DICOM-compliant interface. A qualified medical professional uses the Pinnacle® RTP for functions such as viewing and analyzing the patient's anatomy, and generating a radiation therapy plan.
This 510(k) submission for the Philips Medical Systems (Cleveland), Inc. Pinnacle3 Radiation Therapy Planning System (Pinnacle3 RTP) primarily focuses on demonstrating substantial equivalence to a predicate device, the Computerized Medical Systems, Inc. Xio RTP System - Proton Spot Scanning (K102216), rather than detailing specific acceptance criteria and a study to prove they are met in a quantitative manner. Regulatory submissions for radiation therapy planning systems often rely on verification and validation activities to ensure the software performs as intended and is safe and effective when compared to a legally marketed predicate device.
However, based on the provided text, here's a breakdown of the information requested, with indications where details are not explicitly provided:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not explicitly present a table of quantitative acceptance criteria for features like dose calculation accuracy or planning capabilities, nor does it provide specific device performance metrics in a pass/fail format typical of quantitative studies. Instead, it relies on demonstrating similar functionalities and computational approaches to a predicate device.
The "Non-Clinical Tests" section mentions that "Verification tests were written and executed to ensure that the system is working as designed. Pass/fail requirements and results of this testing can be found in the Thunder Core Verification Test Report, which is included in section 16 of this submission. Pinnacle3 RTP successfully passed verification testing." This suggests that internal acceptance criteria and performance thresholds existed and were met, but these specific details are not included in the provided excerpt.
The comparison table (Table 5A) highlights technological characteristics and principles of operation, implying that similarity to the predicate device in these aspects serves as a primary "acceptance criterion" for substantial equivalence.
Characteristic / "Acceptance Criterion" | Reported Device Performance (Pinnacle3 RTP) |
---|---|
Intended Use | Software package intended to provide planning support for the treatment of disease processes, utilizing photon, proton, electron, and brachytherapy techniques. Assists clinicians in formulating treatment plans to maximize dose to treatment volume and minimize dose to normal tissues. |
Dose Engine: passive double scattering | Pencil beam algorithm based on published work by L. Hong et al. (1996). |
Dose Engine: uniform scanning | Pencil beam algorithm based on published work by L. Hong et al. (1996). |
Dose model parameter values and related functions | Measured data is imported and fitted to models based on published works by A. Somov et al. (poster), H. Szymanowski et al. (2001), T. Bortfeld (1997), and Schaffner, B. (2008) for input into the dose engine. |
Vendor Independent Beam modifier | Yes, uses standard ray tracing and projection techniques. Materials, limitations of size and thickness, physical milling techniques and limitations are all modeled. |
Export plan parameters required by DICOM-RT Ion standard | Yes |
DICOM RT-Dose import and export | Yes |
Mixed Modality Planning | Yes. Dose is combined by summing up dose values from each modality in units of Co-60 equivalent Radiobiological Effective dose. |
Quality Assurance | Yes. Plan and physics reports, compensator and aperture printing, dose calculations in QA phantom, etc., are supported. |
Beam Weight Optimization of Proton Beams | Simple point based method. No full 3D dose optimization performed - Monitor Units of pre-calculated, static beams adjusted only to meet point dose criteria. |
Compensator Modification (Manual and Automatic) | Compensator thickness values are calculated from ray tracing techniques by determining the difference in Water Equivalent Distance for each ray that intersects the target for irradiation. Physical milling techniques are incorporated. User has manual and automated tools, with automated tools based on published work by M. Urie et al. (1983). |
Verification Testing (General Functionality & Design Specifications) | Successfully passed verification testing as documented in the internal "Thunder Core Verification Test Report" (not provided in this excerpt). Hazard analysis completed and mitigated. Verification and Validation test plans followed Philips procedures. |
Dose Calculation Accuracy | Algorithm testing was performed in a QA "Phantom" to compare calculated against measured doses. (No specific numerical acceptance criteria or performance results are provided in this excerpt). |
Clinical Validation (User Experience/Workflow) | Clinical-oriented validation test cases were written and executed by PMS customers at External evaluation sites with oversight by PMS customer support personnel. (No specific acceptance criteria or quantitative results provided in this excerpt). |
2. Sample Size Used for the Test Set and Data Provenance
- Test Set Sample Size: Not explicitly stated. The document mentions "algorithm testing was performed in a QA 'Phantom'" and "clinical orientated validation test cases were written and executed by PMS customers at External evaluation sites." However, the number of phantom configurations, patient cases (if simulated), or specific test sets used in these validations is not provided.
- Data Provenance:
- Phantom Data: For "Algorithm testing... in a QA 'Phantom'", the data is synthetically generated or acquired in a controlled lab environment. This is typically internal, not from a specific country of origin in the clinical sense.
- Clinical-Oriented Validation: For "clinical orientated validation test cases... executed by PMS customers at External evaluation sites," the data would likely be based on simulated or mock patient cases, or potentially anonymized clinical data provided by these "PMS customers." The countries of origin for these "External evaluation sites" are not specified, nor is whether the data was retrospective or prospective. It is implied to be retrospective or simulated to prevent patient exposure to risk.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
- Number of Experts: Not explicitly stated.
- Qualifications of Experts: For the "clinical orientated validation test cases," it mentions "oversight by PMS customer support personnel." It also states that treatment plans "are to be evaluated, modified, and implemented by qualified medical personnel." While this implies that qualified personnel are involved in the validation, their specific roles (e.g., medical physicists, radiation oncologists, dosimetrists) and years of experience are not detailed as "experts establishing ground truth." For the QA phantom testing, the "ground truth" (measured doses) would be established by the physical measurements themselves, typically verified by medical physicists via dosimetry.
4. Adjudication Method for the Test Set
Not explicitly stated. The document refers to "oversight by PMS customer support personnel" for clinical validation, but it doesn't describe any formal adjudication process for disagreements or discrepancies. For phantom testing, the "ground truth" is measured data, and the comparison is usually direct.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No. The document explicitly states: "Clinical trials were not performed as part of the development of this product." Therefore, a multi-reader multi-case (MRMC) comparative effectiveness study focusing on human readers' improvement with AI vs. without AI assistance was not conducted or reported. The device is a planning system, not an AI-assisted diagnostic or interpretation tool in the typical sense of MRMC studies.
6. Standalone (Algorithm Only) Performance Study
Yes, in part. "Algorithm testing was performed in a QA 'Phantom' to compare calculated against measured doses to ensure dose calculation accuracy." This constitutes a standalone performance evaluation of the dose calculation algorithm.
7. Type of Ground Truth Used
- Algorithm Testing: "Measured doses" in a QA "Phantom." This refers to physical measurements in a controlled environment as the ground truth.
- Clinical-Oriented Validation: This implicitly relies on the consensus of "qualified medical personnel" and "PMS customer support personnel" validating that the plans generated by the system are clinically appropriate and meet intended goals. However, a formal "ground truth" establishment process for these cases is not described beyond this general validation.
8. Sample Size for the Training Set
Not applicable. This device is a radiation therapy planning system that uses established physics models and algorithms (e.g., pencil beam algorithm, dose model parameter fitting to published works and measured data) rather than a machine learning model that requires a distinct "training set" in the context of deep learning or AI. The algorithms are based on fundamental physics principles and validated against measured data and published literature.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there isn't a "training set" in the machine learning sense. The models used (e.g., pencil beam algorithm) are derived from fundamental physics and validated against "measured data... fitted to models based on published works." This fitting process uses measured physical data (e.g., Bragg Peak, Spread Out Bragg Peak, Effective SAD, Virtual SAD, Effective Source Size, CT-Number to Stopping Power Tables) as its "ground truth" for parameter derivation.

The data processed may be derived from any nuclear medicine camera. EBW NM 2.0 should only be operated by qualified healthcare professionals trained in the use of nuclear medicine equipment.
EBW NM 2.0 is a Windows®-based Nuclear Medicine suite of image display and processing applications for the Nuclear Medicine market segment. The software package is deployable on hardware platforms, which meet the minimum requirements needed to run the software. The comprehensive tools and features provided with this product, will allow the technologist and/or physician to perform image review, processing of source data, post processing, hardcopy production, interpretation, report generation and contains the utilities necessary to support the workflow and data management between those activities.
The provided document is a 510(k) summary for the Philips EBW NM 2.0 Image Processing System. It states that the device is "substantially equivalent" to predicate devices based on similar intended use, technological comparison, and system performance. However, it does not contain the specific details of performance studies, acceptance criteria, or ground truth establishment that you are requesting.
The 510(k) process primarily focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than presenting detailed performance data against specific acceptance criteria. This document describes the device, its intended use, and its equivalence to two predicate devices (NM Application Suite K080961 and AutoSPECT K090403).
Therefore, based solely on the provided text:
- A table of acceptance criteria and the reported device performance: Not provided. The document states "system performance" but does not detail how this was measured against specific criteria.
- Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not provided.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience): Not provided.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not provided.
- If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance: Not indicated or described. The device is an "Image Processing System" and while it may assist human readers, a formal MRMC study is not mentioned as part of this submission.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not indicated or described.
- The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not provided.
- The sample size for the training set: Not provided.
- How the ground truth for the training set was established: Not provided.
In summary, this 510(k) summary confirms the regulatory clearance of the device but does not include the detailed study information or performance metrics you've asked for. Such information, if generated, would typically be found in detailed internal validation reports or potentially in a more comprehensive clinical study report, neither of which is part of this 510(k) "summary of safety and effectiveness."

A nuclear medicine image display and processing application suite that provides software applications used to process, analyze and display medical images/data. The results obtained may be used as a tool, by a nuclear physician, in determining the diagnosis of patient disease conditions in various organs, tissues, and other anatomical structure. The data processed may be derived from any nuclear medicine gamma camera. JETPack 2.0 should only be operated by qualified healthcare professionals trained in the use of nuclear medicine equipment.
JETPack 2.0 is a Windows®-based Nuclear Medicine suite of image display and processing applications for the Nuclear Medicine market segment. The software package is deployable on hardware platforms, which meet the minimum requirements needed to run the software. The comprehensive tools and features provided with this product, will allow the technologist and/or physician to perform image review, processing of source data, post processing, hardcopy production, interpretation, report . generation and contains the utilities necessary to support the workflow and data management between those activities.
This 510(k) summary does not contain the information requested for acceptance criteria or specific study details to prove the device meets acceptance criteria.
The document is a premarket notification for a new version of a Picture Archiving and Communication System (PACS) software, JETPack 2.0. It primarily focuses on establishing substantial equivalence to a predicate device (Philips Medical Systems NM Application Suite, K080961).
Here's why the requested information is not present:
- Acceptance Criteria and Reported Device Performance: This document states that JETPack 2.0 and the predicate device "perform in a similar manner with respect to, display, review and processing applications." It concludes that JETPack 2.0 is "substantially equivalent based on similar intended use, technological comparison, and system performance." However, it does not define specific acceptance criteria (e.g., quantitative metrics, thresholds) or present a table of reported device performance against such criteria. The "system performance" is described in a general, rather than a quantifiable, manner.
- Sample Size for Test Set and Data Provenance: This information is not provided. No specific test set or clinical study data is referenced.
- Number of Experts and Qualifications: This information is not provided. There's no mention of experts establishing ground truth for a test set.
- Adjudication Method: Not applicable, as no test set requiring adjudication is mentioned.
- Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study: No MRMC study is mentioned. The document relies on substantial equivalence to a previous device rather than a new comparative effectiveness study.
- Standalone Performance: While the description focuses on the software's functionality, there's no standalone performance study in the context of diagnostic accuracy or clinical impact presented here.
- Type of Ground Truth Used: Not applicable, as no specific ground truth for a performance study is described.
- Sample Size for Training Set: This information is not provided. The development process of the software, including any training data for AI/ML components (if present, which is not explicitly stated for this 2011 submission), is not detailed.
- How Ground Truth for Training Set Was Established: Not applicable, as no training set or its ground truth establishment is described.
In summary, this 510(k) filing demonstrates substantial equivalence by comparing the device's intended use and general technological characteristics to a legally marketed predicate device. It does not present detailed performance studies with specific acceptance criteria, test sets, or ground truth establishment that would be required for innovative devices making new claims or for devices undergoing more rigorous evaluation pathways.
