The portable X-ray unit is intended to be used only when stand/tripod mounted.

The PRORAD ATLAS ULTRAPORTABLE X-ray digital system is predominantly employed in various settings, including health-care centres, temporary and emergency health centres (established, especially in pandemic circumstances), outreach and field interventions (such as mobile clinics/vans, screening campaigns, and home care), and tele-radiology solutions in remote areas.

The primary users anticipated for the system include radiographers, radiological technologists, and medical professionals who are trained in safety, radiation protection, and image management.

The PRORAD ATLAS ULTRAPORTABLE PLUS Digital X-ray system is intended to deliver high-quality, diagnostic radiographic images of the body extremities. It utilizes a portable X-ray Unit, flat-panel detector and real-time image processing using software to produce clear digital images, enabling fast and accurate diagnosis. The portable X-ray unit is intended to be used only when stand/tripod mounted.

The PRORAD ATLAS ULTRAPORTABLE PLUS X-ray digital system is predominantly employed in various settings, including health-care centres, temporary and emergency health centres (established, especially in pandemic circumstances), outreach and field interventions (such as mobile clinics/vans, screening campaigns, and home care), and tele-radiology solutions in remote areas.

The primary users anticipated for the system include radiographers, radiological technologists, and medical professionals who are trained in safety, radiation protection, and image management.

The PRORAD ATLAS X-Ray system includes the ULTRAPORTABLE and ULTRAPORTABLE PLUS, which are portable diagnostic X-ray systems with fixed 70kV and 2mA tube current. These systems are intended to produce anatomical X-rays of the body extremities in both pediatric and adult patients. The PRORAD ATLAS X-Ray system was designed, developed, and manufactured by Prognosys Medical Systems Private Limited. The model numbers are listed below.

The PRORAD ATLAS X-ray system is a sophisticated, battery-powered X-ray generator offered in two versions: PRORAD ATLAS ULTRAPORTABLE and ULTRAPORTABLE PLUS. The main distinction between these models lies in their exposure time ranges and target anatomical areas. The ULTRAPORTABLE model provides exposure times ranging from 0.01 to 1.30 seconds, while the ULTRAPORTABLE PLUS model offers an extended exposure range of 0.01 to 2.5 seconds. Both models share identical internal components, software, algorithms, and operational features and are intended for imaging body extremities. The system includes a high-voltage tank with an X-ray tube mounted on an adjustable tripod stand, allowing users to adjust the height to the specific imaging area. Exposure parameters are configured through the X-ray generator's graphical user interface (GUI). After setting the parameters and positioning the patient on the detector, the X-ray is activated via an exposure switch. The detector captures the radiation, converts it into a digital signal, and transmits the data wirelessly to a computer equipped with compatible software. The images are processed and displayed on the computer for diagnostic review. The PRORAD ATLAS system is compatible with several 510(k)-cleared detectors and their associated software, listed below in Table 1. Prognosys includes one detector and its pre-configured software in the package, depending on availability. Fully battery-operated, the system does not support direct power connection but can seamlessly integrate with multiple detectors and compatible software as part of the package.

The provided FDA 510(k) clearance letter and supporting documentation for the PRORAD ATLAS ULTRAPORTABLE X-Ray Systems do not include acceptance criteria or a detailed study that proves the device meets specific performance criteria beyond general safety and effectiveness.

The document primarily focuses on demonstrating substantial equivalence to a predicate device (Remex KA6, K212144) rather than presenting a performance study with defined acceptance criteria. The "Summary of non-clinical testing" lists a series of international standards (IEC, ISO) and FDA guidance documents that were followed for design control, risk management, verification, and validation. The "Summary of clinical testing" mentions that clinical images were collected and reviewed by a qualified radiologist, confirming they are "clinically acceptable." However, specific quantitative acceptance criteria for image quality, diagnostic accuracy, or other performance metrics, along with the study design and results against those criteria, are not detailed in this document.

Therefore, I cannot provide a table of acceptance criteria and reported device performance, nor can I provide information about sample size, expert details, adjudication methods, MRMC studies, standalone performance, or training set specifics, as this information is not present in the provided text.

Based on the available text, here's what can be extracted:

• Overall Conclusion: The device is deemed "safe and effective when the device is used as labelled and is substantially equivalent to the predicate device."

Here's a breakdown of why the requested information cannot be fully provided based on the input:

1. A table of acceptance criteria and the reported device performance: This information is not explicitly stated in the document. The document confirms that "Validation of PRORAD ATLAS X-Ray System has demonstrated that the system enables optimal and quality imaging of anatomical structures" and that clinical images are "clinically acceptable," but no specific quantitative criteria or performance metrics are given.

2. Sample size used for the test set and the data provenance: The document states that "Clinical images of body extremities were collected from patients of varying ages, weights, and BMIs." However, the exact sample size and the provenance (e.g., country of origin, retrospective/prospective nature) of this clinical image test set are not specified.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: The document mentions that images were "reviewed by a qualified radiologist." It does not specify the number of radiologists or their specific qualifications (e.g., years of experience, board certification).

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: No adjudication method for the clinical image review 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: An MRMC study is not mentioned. The device described is an X-ray system, not an AI software to assist human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: This is not applicable as the device is an X-ray system, not an algorithm, and it's intended to be used by trained medical professionals.

7. The type of ground truth used: The ground truth for the clinical images appears to be "clinical acceptability" as determined by a "qualified radiologist." This aligns with "expert consensus" in a general sense, but no more objective ground truth (e.g., pathology, outcomes data) is mentioned for the image quality assessment.

8. The sample size for the training set: The document does not mention a training set, as it describes an X-ray hardware system, not an AI-driven software that requires a training set.

9. How the ground truth for the training set was established: Not applicable, as no training set is mentioned.

The GXR-Series Diagnostic X-ray System is intended for use in obtaining human anatomical images for medical diagnostic by using X-rays.

The GXR Series Diagnostic X-ray System consists of a combination of an x-ray generator, and associated equipment such as tube stand, patient table, and, digital imaging system.

Here's an analysis of the provided text regarding acceptance criteria and supporting studies for the GXR-series diagnostic x-ray system:

It's important to note that the provided document is a 510(k) Summary, which is a regulatory filing for a medical device seeking clearance from the FDA based on substantial equivalence to a predicate device. It typically focuses on demonstrating that the new device is as safe and effective as a legally marketed device, rather than proving absolute performance against specific clinical acceptance criteria in a comprehensive clinical study. Therefore, the details provided often lean towards non-clinical testing and comparison with established standards.

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of "acceptance criteria" for clinical performance. Instead, it relies on demonstrating adherence to recognized safety and performance standards, and comparison of technical characteristics to a predicate device. The "performance" is implicitly deemed acceptable if the device meets these standards and is substantially equivalent to the predicate.

Here's a generalized interpretation based on the document's content, focusing on what would typically be implied performance requirements for an X-ray system:

2. Sample Size Used for the Test Set and Data Provenance

• Test Set Sample Size: The document does not specify a "test set" sample size in terms of clinical images or patient cases for performance evaluation against specific acceptance criteria. The testing discussed is primarily non-clinical, related to hardware and software verification and validation.
• Data Provenance: The document implies that the testing data is generated from laboratory testing and verification during the development and modification of the device. There is no mention of clinical data or patient data being used for the performance evaluation in this 510(k) summary. Given the context of a 510(k), particularly for an X-ray system, the primary focus is on engineering and performance testing against standards, rather than large-scale clinical studies. The data is thus likely prospective in terms of being generated specifically for this submission but is non-clinical in nature.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

This information is not provided in the document. As the evaluation is non-clinical, there is no mention of "ground truth established by experts" in the context of diagnostic performance evaluation. The "ground truth" for non-clinical testing would typically be the expected technical output or adherence to a standard, rather than expert interpretation of images.

4. Adjudication Method for the Test Set

This information is not provided as the testing described and implied is non-clinical and does not involve expert adjudication of diagnostic findings.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and effect size

No, a multi-reader multi-case (MRMC) comparative effectiveness study was not explicitly mentioned or performed as part of this 510(k) submission. The document focuses on demonstrating substantial equivalence through technical comparisons and compliance with standards, not on proving improved reader performance with or without AI assistance.

6. If a Standalone (algorithm only without human-in-the-loop performance) was done

This is not applicable in the sense of an AI algorithm's standalone performance. The device is a diagnostic X-ray system, which is inherently designed to be used with a human interpreter (a medical professional). While it has image processing software ("RADMAX"), this software enhances images for human diagnosis, not to provide an automated diagnosis itself.

7. The Type of Ground Truth Used

The "ground truth" for the non-clinical testing is adherence to technical specifications and international standards. For example, for radiation output, the ground truth is that the device delivers the specified kVp and mA, and for electrical safety, that it meets the requirements of IEC 60601-1. For image quality, it refers to intrinsic properties like spatial resolution, MTF, and DQE, which are measured objectively, not subjective expert consensus on diagnostic findings.

8. The Sample Size for the Training Set

This information is not applicable and therefore not provided. The device is an X-ray imaging system, not an AI/ML diagnostic algorithm that requires a training set of medical images in the conventional sense. The "training" for the device would involve calibration and configuration during manufacturing and installation to ensure it meets its technical specifications. The "RADMAX" software has image processing modules, but the document does not suggest these are deep learning models trained on vast datasets.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable for the same reasons as #8. If any parameters for the image processing modules are "learned" or optimized, the document does not elaborate on this process or the ground truth used for such optimization.

The core part of x-ray source adopts high quality tube assembly, motorized x-ray collimator. HV cable assembly and High Voltage X-Ray Generator. Touch screen LCD based x-ray control console provides user-friendly interface and easy technique selection. Collimator supports high accuracy for selected x-ray field size over any SID. Direct radiography via flat panel detector improves-exam speed and comfort with efficiency. Digital flat panel detector with Csl screen provides spatial resolution, MTF, DQE and stability based on fine pixel pitch. Selection of an anatomical study on the Digital Imaging Software automatically sets up the x-ray generator's preprogrammed exposure technique. The types of "TOPAZ" system are divided into TOPAZ-32D, and TOPAZ-40D according to maximum power and mA. The higher the maximum output, the wider the mA range to choose from, giving the user more technical options to choose from. The "TOPAZ Mobile X-ray System" consists of a tube assembly. x-ray collimator. High Voltage X-Rav Generator, detector and mechanical parts for mobility.

The provided text is a 510(k) Summary for the TOPAZ Mobile X-ray System, which focuses on demonstrating substantial equivalence to a predicate device rather than presenting a performance study with acceptance criteria in the format typically used for AI/CADe devices. This document describes the device, its intended use, technological characteristics, and differences from the predicate, along with non-clinical testing for safety and EMC standards.

Therefore, the specific information about "acceptance criteria and the study that proves the device meets the acceptance criteria" as requested for AI/CADe devices (including details like sample size for test sets, data provenance, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, type of ground truth, and training set details) is not present in this 510(k) Summary.

This document primarily asserts that the "TOPAZ Mobile X-ray System" is substantially equivalent to the predicate device "TOPAZ Mobile DR System (K201124)" based on:

• Identical intended use.
• Similar technological characteristics, with modifications thoroughly tested for safety and effectiveness against international standards.
• Nonclinical testing results provided in the 510(k) demonstrating that predetermined acceptance criteria were met for safety (electrical safety, EMC, radiation protection) and software validation.

The "study that proves the device meets the acceptance criteria" in this context refers to the nonclinical testing against various recognized international and FDA standards, not a clinical performance study with human readers or pathology, as would be expected for AI/CADe systems.

Here's a summary of the available information regarding acceptance criteria and testing, tailored to what is provided in the document:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not explicitly present a table of acceptance criteria and reported device performance in the typical format for clinical accuracy for AI/CADe. Instead, it states that the device was assessed, tested, and passed predetermined testing criteria during validation testing, aligning with the risk analysis. It also confirms that the device meets "all the requirements listed in the Standards" (see the Standards table below). The "device performance" reported is its conformance to these standards and its substantial equivalence to the predicate.

Nonclinical Standards Met (acting as acceptance criteria for safety and effectiveness):

2. Sample size used for the test set and the data provenance:

• Not Applicable/Not Provided. The document describes non-clinical engineering and software validation testing against standards, not a clinical study involving a "test set" of patient data for diagnostic performance. The focus is on the device's hardware, software (RADMAX), and new flat panel detectors meeting safety and electrical standards.

3. 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/Not Provided. Ground truth establishment by experts is relevant for clinical performance studies, which this document does not describe.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

• Not Applicable/Not Provided. This is relevant for clinical performance studies.

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:

• No. This document describes a 510(k) for an X-ray system, not an AI/CADe system. No MRMC study was performed or is mentioned.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:

• Not Applicable/No. The device itself is an X-ray system, not an algorithm, and its performance is assessed in terms of meeting engineering and regulatory standards, not standalone diagnostic performance. The imaging software (RADMAX) is mentioned as identical to the predicate and has a "Basic Documentation Level" of concern, implying human interpretation of images.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

• Not Applicable/Not Provided. For the non-clinical testing described, "ground truth" would relate to the correct functioning of the hardware and software according to specifications and standards, not clinical diagnostic accuracy.

8. The sample size for the training set:

• Not Applicable/Not Provided. This is relevant for AI/ML models. While the device contains software, it is not described as an AI/ML diagnostic algorithm needing a training set. The software changes are primarily GUI and image processing module updates, verified for impact on safety and effectiveness (not AI training).

9. How the ground truth for the training set was established:

• Not Applicable/Not Provided. As above, this is not an AI/ML submission requiring a training set.

In summary, the provided 510(k) document is for a mobile X-ray system and demonstrates substantial equivalence through nonclinical testing against recognized performance, safety, and EMC standards, rather than a clinical performance study with acceptance criteria related to diagnostic accuracy, which would be typical for AI-powered diagnostic devices.

I am sorry, but the provided text does not contain the detailed information required to describe the acceptance criteria and the study that proves the device meets those criteria. Specifically, the document is a 510(k) summary for a medical device (AcuityDR G4) and focuses on demonstrating substantial equivalence to a predicate device.

The document discusses performance characteristics of the digital panels (DQE, MTF, resolution) and indicates that clinical image evaluation was performed on the proposed panels by a Board Certified Radiologist who found the images to be of excellent quality. However, it does not provide explicit acceptance criteria, a structured study design with specific metrics, or details about patient data, expert qualifications, or ground truth establishment in the way requested.

Here's a breakdown of why I cannot fulfill your request based on the provided text:

1. Table of acceptance criteria and reported device performance: While performance characteristics like DQE and MTF values are reported, these are not presented as acceptance criteria in the context of a specific study to prove the device meets them. There's no clear threshold or target defined that the device needs to achieve to be considered "acceptable" in a formal study sense.

2. Sample size used for the test set and data provenance: The document mentions "clinical image evaluation" was performed but does not specify the sample size of images or patients used. It also doesn't provide details on the data's origin (country, retrospective/prospective).

3. Number of experts used to establish the ground truth and qualifications: It states "a Board Certified Radiologist" performed clinical image evaluation, implying one expert. However, their specific qualifications (e.g., years of experience, specific sub-specialty) are not provided beyond being "Board Certified." The method for establishing "ground truth" (if any beyond the radiologist's assessment) is not described.

4. Adjudication method: Not mentioned.

5. Multi-reader multi-case (MRMC) comparative effectiveness study: Not mentioned and typically not required for substantial equivalence claims for this type of device (an X-ray system). The evaluation described is a qualitative assessment of image quality by a radiologist. There is no mention of comparing human readers with and without AI assistance.

6. Standalone (algorithm only) performance: Not applicable here as the device is an X-ray system, not an AI algorithm performing diagnostic tasks independently. The software provided is for controlling the X-ray generator and image acquisition, not for diagnostic interpretation.

7. Type of ground truth used: The text indicates a "Board Certified Radiologist" evaluated image quality. This suggests expert consensus (though with only one expert mentioned) on image quality, but not pathology or outcomes data.

8. Sample size for the training set: Not applicable and not mentioned, as this device itself is not a machine learning algorithm requiring a training set for diagnostic classification.

9. How the ground truth for the training set was established: Not applicable.

The document mainly focuses on comparing the AcuityDR G4 system's technological characteristics (like detector DQE, MTF, and resolution) and indications for use to its predicate device (AcuityDRe, K210919) and other reference devices, concluding that the new device is substantially equivalent. The image quality evaluation by the radiologist appears to be a supportive qualitative assessment rather than a structured quantitative study with predefined acceptance criteria.

It supports the single frame mode, with the key component of TFT/PD image sensor flat panel of active area: 33.18cm×25.28cm. The sensor plate of Mars1013X is direct-deposited with CsI(Cesium Iodide) scintillator to achieve the conversion from X-ray to visible photon. The visible photons are transformed to electron signals by diode capacitor array within TFT panel, which are composed and processed by connecting to scanning and readout electronics, consequently to form a panel image by transmitting to PC through the user interface. The major function of the Mars1013X is to convert the X-ray to digital image, with the application of high resolution X-ray imaging. Both kinds of detectors are the key component of DR system, enable to complete the digitalization of the medical X-ray imaging with the DR system software. iRay SDK(include iDetector) is intended to supply API interface for DR system manufacturers. DR system manufacturer control the detector by SDK interface. SDK is not intend to be used directly by other users beside DR system manufacturers.

The provided text is a 510(k) summary for the iRay Technology Taicang Ltd. Wireless Digital Flat Panel Detector (Mars1013X). It describes the device, its intended use, and its comparison to predicate devices to demonstrate substantial equivalence.

However, the document does NOT contain information about specific acceptance criteria related to a study proving the device meets those criteria in the context of AI/algorithm performance. It primarily focuses on the device's physical and technical specifications, electrical safety, biological evaluation, and comparison to predicate devices, but not on clinical performance metrics that would typically be established for an AI-powered diagnostic device.

The provided text describes a "Wireless Digital Flat Panel Detector", which is a hardware component for X-ray imaging, not an AI or algorithmic diagnostic device. Therefore, the questions related to AI-specific acceptance criteria, test sets, ground truth establishment, expert adjudication, MRMC studies, and standalone algorithm performance are not applicable to the information contained in this document.

The document states:

• "Mars1013X Wireless Digital Flat Panel Detector is the kind of wireless digital flat panel detector. It supports the single frame mode, with the key component of TFT/PD image sensor flat panel of active area: 33.18cm×25.28cm"
• "The major function of the Mars1013X is to convert the X-ray to digital image, with the application of high resolution X-ray imaging."

The performance metrics discussed (Spatial Resolution, MTF, DQE) are physical imaging characteristics of the detector itself, not diagnostic performance of an AI analyzing the images.

Therefore, it is not possible to extract the requested information regarding acceptance criteria and a study proving an AI device's performance from the provided text. The document pertains to the clearance of an X-ray detector, not an AI diagnostic algorithm.
