VisiRad XR is a computer-aided detection (CADe) device intended to identify and mark regions of interest that may be suspicious for lung nodules and masses on chest radiographs. It identifies features associated with pulmonary nodules and masses from 6-60mm in size. Detection of suspicious findings by VisiRad XR is intended as an aid only after the physician has performed an initial interpretation; it is not intended to replace the review by a qualified radiologist and is not intended to be used for trage or to make or confirm a diagnosis. The intended patient population for VisRad XR consists of patients >21 years of age on whom chest radiographs have been acquired in an outpatient or emergency department setting.
VisiRad XR is a computer aided detection (CADe) software as a medical device (SaMD) product intended to detect lung nodules and masses from 6-60mm in chest radiographs. VisiRad XR takes DICOM images as input, utilizes machine learning algorithms to detect suspicious regions and outputs a secondary DICOM with annotated regions of interest (ROIs). VisiRad XR's output secondary DICOM includes text that it was analyzed by VisiRad XR and a link to the user manual. If no ROIs are detected by VisiRad XR, the returned secondary DICOM states "No Nodules/Masses Found". VisiRad XR is intended to be used as a second-read only after the clinician has performed their initial interpretation. The secondary DICOM does not overwrite or replace the primary radiograph, it is returned such that it hangs, using standard DICOM hanging protocol, behind the primary image.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
The document refers to "bench tests" and does not specify sample sizes (e.g., number of specimens for each test like compressive strength). It implies in-house testing was performed for the IMICRYL products to generate the reported data. The country of origin for the data generation (testing) would likely be Turkey, where the manufacturer (IMICRYL DIS MALZEMELERI SANAYI VE TICARET A.S.) is located. These are laboratory-based, non-clinical tests, not human subject data.
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)
This question is not applicable to this type of device submission. There were no human experts establishing "ground truth" as it relates to image interpretation or clinical outcomes. The "ground truth" for material properties is established by adherence to recognized international standards (e.g., ISO 4049, ISO 17304) and laboratory testing methodologies.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable. This is a non-clinical bench testing submission, not an clinical study requiring expert adjudication of data.
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 document is for a dental restorative material, not an AI-enabled diagnostic device. No MRMC study was performed.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is not an AI/ML algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for this submission are the physical, mechanical, and biological properties of the material, measured through standardized non-clinical bench tests (e.g., compressive strength, flexural strength, biocompatibility tests). These measurements are quantifiable and objective, not dependent on expert consensus, pathology, or outcomes data in the way medical imaging AI devices are. The "truth" is established by laboratory measurements according to ISO standards.
8. The sample size for the training set
Not applicable. There is no training set as this is not an AI/ML device.
9. How the ground truth for the training set was established

Nova Resin dual cure, self adhesive resin cementation of all indirect restorations including ceramic, resin and metal-based inlays, onlays, bridges, posts and veneers. *
Additional indications include core-buildup material, pit and fissure sealant, and cementation of crowns restorations to implants.
- Adhesive application on the prep is required for veneer cementation using Nova Resin dual cure, self adhesive resin cement.
Resin Cement dual cure, self adhesive resin cement for the cementation of indirect restorations made of high strength all ceramic, composite, metal-ceramic and metal.
When Resin Cement dual cure, self adhesive resin cement is used, additional bonding agents are not required. The automix double syringe enables saving time direct application of the luting cement into restoration.
This document, an FDA 510(k) summary for the "NOVA RESIN dual cure, self adhesive resin cement," describes the device and its equivalence to a predicate device, but it does not describe an AI/ML device or its associated acceptance criteria and study data.
The document focuses on the physical and chemical properties of a dental cement. The "acceptance criteria" and "reported device performance" provided in the table are for these physical properties (e.g., film thickness, flexural strength), not metrics related to AI/ML performance like sensitivity, specificity, or AUC.
Therefore, I cannot extract the information requested regarding a study proving an AI/ML device meets acceptance criteria, as this document does not pertain to an AI/ML device.
Here's why the requested information cannot be found in the provided text:
- No mention of AI/ML device or algorithm: The entire document describes a dental cement and its physical properties. There is no mention of algorithms, machine learning, artificial intelligence, or any form of software that processes data for diagnostic or predictive purposes.
- Acceptance criteria are for physical properties: The table provided lists metrics such as Film Thickness, Working Time, Flexural Strength, etc. These are standard engineering and material science metrics for dental cements, not performance metrics for an AI system.
- No "test set," "training set," "ground truth," or "experts" in the AI context: These terms are specific to the validation of AI/ML models. The document refers to "non-clinical performance testing" which are bench tests, not clinical studies involving human experts or patient data for AI validation.
- No MRMC study: A Multi-Reader Multi-Case study is a type of clinical trial specifically designed to evaluate the impact of AI on human reader performance in medical imaging. The provided document does not mention any clinical studies of this nature.
- No "standalone performance": "Standalone" performance refers to the algorithm's performance without human intervention. This is irrelevant for a dental cement.
In summary, this document is a regulatory submission for a dental material, not an AI/ML medical device.

- . Nova Glass Cements are based on the reaction of silicate glass powder and polyalkeonic acid. (acid-base reaction)
- . Nova Glass Cements are formulated to provide a powder and a liquid portion. In use the two are combined and a chemical reaction takes place to provide set cement.
The provided text is a 510(k) Premarket Notification for dental cements (Nova Glass Cements). This document focuses on demonstrating substantial equivalence to existing legally marketed devices, primarily through comparison of indications for use, functional characteristics, composition, and physical properties, along with biocompatibility testing results.
Crucially, this document does not describe a study involving an AI/software device that requires human expert review for ground truth or MRMC studies. The device in question is a material-based dental cement. Therefore, many of the requested elements related to AI algorithm performance (e.g., sample size for test set, data provenance, number of experts for ground truth, adjudication method, MRMC studies, standalone performance, training set details) are not applicable to this type of medical device submission.
The "acceptance criteria" and "study that proves the device meets the acceptance criteria" in this context refer to the physical and biological properties testing conducted on the dental cements themselves, to show they perform comparably to their predicate devices and meet established standards for safety and effectiveness.
Here's a breakdown of the relevant information provided in the document:
Acceptance Criteria and Device Performance (for a Dental Cement)
1. Table of Acceptance Criteria and Reported Device Performance
The document does not present a formal table of "acceptance criteria" against which a study directly proves the device meets them in the way one might for an AI algorithm's performance metrics (e.g., sensitivity, specificity). Instead, it demonstrates substantial equivalence by comparing the physical properties of the new device to its predicate devices and showing biocompatibility testing results against general safety standards.
Here's how the information can be presented for the dental cements, drawing from Section "PHYSICAL PROPERTIES" on page 7 and "NON-CLINICAL PERFORMANCE TESTING" on page 8.
| Acceptance Criteria Category | Specific Test/Property | Predicate Device Standard / Expected Range (Implied by Predicate) | Reported Device Performance (Nova Glass Cements) |
|---|---|---|---|
| Physical Properties | Powder/Liquid Ratio | Matching predicate values for each product type | Matched predicate values (e.g., Nova Glass L & ProGlass One: 2.4/1.0, Nova Glass F & ProGlass Two: 3.5/1.0, etc.) |
| Mixing Time | 30 seconds (for all predicate products) | 30 seconds (for all Nova Glass products) | |
| Working Time | Matching predicate values for each product type | Matched predicate values (e.g., Nova Glass L: 2'30"-3", Nova Glass F: 1'30"-2', etc.) | |
| Setting Time | Matching predicate values for each product type | Matched predicate values (e.g., Nova Glass L: 3'10", Nova Glass F: 3'10"-3', etc.) | |

| Genotoxicity (OECD 471) | No mutagenic potential | "It does not have mutagenic potential." | |
| Sensitization | No sensitization | "It does not cause sensitization." | |
| Subacute Systemic Toxicity | No subacute systemic effect | "It does not have a subacute systemic effect." | |
| Irritation | No irritation | "It does not cause irritation." | |
| Implantation | No implantation effect | "It does not cause implantation." |
Study Proving Device Meets Acceptance Criteria:
The study that proves the device meets the acceptance criteria is primarily non-clinical performance testing, consisting of:
- Physical Testing: In-vitro bench tests performed on all Nova Glass Cements according to the requirements of ISO 9917-1:2007 (Dentistry - Water-based cements - Part 1: Powder/liquid acid-base cements).
- Biocompatibility Testing: Conducted in accordance with ISO 10993-1 (Biological Assessment Medical Devices - Part 1: Evaluation and Testing) standard, specifically for Nova Glass F as a representative. For other products (Nova Glass LC, Nova Glass BF, Nova Glass L Plus), equivalence is asserted based on existing components in legally marketed devices.
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: The document does not specify exact sample sizes for the physical or biocompatibility tests. For physical properties, it states "In-vitro bench tests were performed." For biocompatibility, it lists test names and "Report Numbers" but not the sample sizes used in those reports.
- Data Provenance: The tests were conducted to support a submission from a Turkish company (IMICRYL DIS MALZEMELERI SANAYI VE TICARET A.S.). The testing itself would likely have been done in a laboratory environment, but the origin of the "data" itself isn't described as retrospective or prospective patient data, as this is a material-based device.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
- Not Applicable: This criterion is for AI/software devices requiring human expert review to establish ground truth. For dental cements, ground truth is established by standardized laboratory testing procedures and the results are objective measurements (e.g., setting time, strength, toxicity).
4. Adjudication Method for the Test Set
- Not Applicable: This is an AI/software specific criterion for resolving discrepancies among human annotators.
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 is an AI/software specific criterion. No human readers or AI assistance are involved in the function or testing of these dental cements.
6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable: This is an AI/software specific criterion. There is no algorithm.
7. The Type of Ground Truth Used
- Objective Laboratory Measurements/Standards:
- Physical Properties: The ground truth for physical properties (e.g., film thickness, setting time, compressive strength) is based on the methods and limits defined in the international standard ISO 9917-1:2007 for water-based cements. The device demonstrates compliance with these established empirical standards and similarity to the predicate devices.
- Biocompatibility: The ground truth for biocompatibility is based on the negative/positive control findings and criteria for safe biological response defined by ISO 10993-1 and specific test methodologies (e.g., OECD guidelines for genotoxicity).
8. The Sample Size for the Training Set
- Not Applicable: This is an AI/machine learning specific criterion. Dental cements do not have a "training set."
9. How the Ground Truth for the Training Set Was Established
- Not Applicable: As above, no training set exists for this device.

R&D Series Nova Compo- B Plus is a Light-cure ethanol/water-based, self-etching, one-step, all in one universal adhesive. It can be used reliably in total-etch or selective-etch mode for both direct and indirect restorations. Depending on the indication, the adhesive is used as self-etching or with phosphoric acid for selective enamel etching procedures. The product is intended to be used for both direct and indirect restorations. The 4-MET RDX multi-functional carboxylate methacrylate polymer creates a 3-dimensional, high-strength bond with calcium. MDP (Methacryloyloxydecyl Dihydrogen Phosphate) monomer binds to Ca+2 ions on all surfaces of the tooth. The R&D Series Nova Compo- B Plus forms a micro-mechanical bond between the dentine channels to form the resin tags. Depending on the indication, the adhesive is used as self-etching or with phosphoric acid for selective enamel etching or total-etching procedures.
The provided text describes a 510(k) premarket notification for a dental bonding agent, R&D Series Nova Compo-B Plus. It assesses the device's substantial equivalence to predicate and reference devices based on indications for use, composition, and physical properties. However, this document does not contain information about an AI/ML-based medical device study that would involve the typical acceptance criteria and study design elements requested in the prompt (e.g., test set sample size, expert ground truth, MRMC studies, standalone performance).
The information provided is for a traditional medical device (a dental adhesive), comparing its physical properties like bond strength, appearance, and curing time to existing, legally marketed dental adhesives. It's a standard regulatory submission for a Class II medical device, focusing on bench testing and biocompatibility.
Therefore, I cannot fulfill the request to describe the acceptance criteria and the study proving an AI/ML device meets those criteria, as the provided text relates to a non-AI/ML dental bonding agent.
Specifically, the document states:
- Trade/Device Name: R&D Series Nova Compo-B Plus Bottle, R&D Series Nova Compo-B Plus Single Dose
- Regulation Name: Resin Tooth Bonding Agent
- Device Description: "R&D Series Nova Compo- B Plus is a Light-cure ethanol/water-based, self-etching, one-step, all in one universal adhesive."
This clearly indicates a chemical and physical product, not an AI/ML software device.

R&D Series Nova Compo N is a light-curing, radiopaque, nano-hybrid universal composite for anterior restorations. It is intended for professional use by below mentioned Indications for Use;
- · Restorations of deciduous teeth
- · Splinting of mobile teeth
- · Restoration in the posterior region (Classes I and II)
- · Anterior restorations (Classes III, IV)
- · Class V restorations (cervical caries, root erosion, wedge-shaped defects)
- · Extended fissure sealing in molars and premolars
- · Veneering of discoloured anterior teeth
- · Repair of composite and ceramic veneers
R&D Series Nova Compo N is a light-curing, radiopaque, nano hybrid composite for anterior and posterior restorations.
According to the applicable FDA recognized consensus standard: ISO 4049:2009 "Dentistry-Polymer Based Restorative Materials", this device is classified into the following:
- -Type 1: polymer-based filling and restorative materials;
-Class 2: Materials whose setting is effected by light;
-Group 1: Materials whose use requires the energy to be applied intra-orally.
R&D Series Nova Compo N light cure nano hybrid composite is designed with the high reduced shrinkage resin. The higher molecular weight of the resin results in less shrinkage, reduced aging and a slightly softer resin matrix. Additionally these resins impart a greater hydrophobicity and are less water absorption. Prepolymerized fillers provide low stress, non-sticky, easy handling and shaping formulation. High loading Prepolymerized fillers provide better wear resistance than traditional less loaded Prepolymerized fillers in other marketing composites. The nanofillers provide high polish, high wear, surface hardness and making the material smooth.
R&D Series Nova Compo N light cure nano hybrid composite was tested for biocompability and found to be biocompatible as a result of testing.
The user is asking for specific details about the acceptance criteria and the study proving the device meets those criteria, based on the provided FDA 510(k) summary.
Here's an analysis of the provided text and the answers to your questions:
The provided document is an FDA 510(k) premarket notification for a dental composite material, R&D Series Nova Compo N. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through extensive clinical trials. Therefore, the "acceptance criteria" and "study that proves the device meets the acceptance criteria" are typically addressed through comparison to established standards (like ISO) and predicate device performance, along with bench testing.
Here's a breakdown of the requested information:
1. A table of acceptance criteria and the reported device performance
The document doesn't explicitly state "acceptance criteria" in a separate section. Instead, it presents the performance of the new device (R&D Series Nova Compo N) in comparison to the performance of its predicate devices, implying that performance similar to or better than the predicates, and adherence to relevant ISO standards, constitutes the "acceptance criteria."
The closest representation of this is Table 1 in the "Substantial Equivalence" section of the document, which compares the physical properties of the new device with its predicates. The "acceptance criteria" can be inferred as being at least equivalent to the predicate devices and meeting the requirements of the ISO 4049:2009 standard.
Inferred Acceptance Criteria and Reported Device Performance (from Table 1 and text):
| Physical Property | Device Acceptance Criteria (Inferred from Predicates & ISO 4049:2009) | R&D Series Nova Compo N Performance |
|---|---|---|
| Compressive Strength (MPa) | ≥ 250 MPa (based on predicate Tetric Evoceram) | 360 |
| Flexural Strength (MPa) | ≥ 118 MPa (based on predicate Clearfil Majesty Esthetic) | 130 |
| Depth Of Cure (mm) | > 1.5 mm (based on predicates) | ≥ 2 |
| Particle Size Range | Similar to predicates (40 nm - 3 µm is acceptable) | 40 nm and 3 µm. |
| Water Sorption (µg/mm³) | ≤ 25.3 µg/mm³ (based on predicate Clearfil Majesty Esthetic) | 21.2 |
| Water Solubility (µg/mm³) | ≤ 1.5 µg/mm³ (based on predicate Clearfil Majesty Esthetic) | < 1.0 |
| Elastic Modulus | Around 10 GPa (consistent with predicates) | 10 GPa |
| Radio-opacity (mm of Al) | Within a functional range for dental composites (e.g., 180%-400%) | 350% |
| Working Time (second) | Similar to predicates (e.g., 200-250 seconds) | 250 |
| Curing Time (second) | Similar to predicates (e.g., 20 seconds) | 20 |
| Sensitivity to Ambient Light (second) | Similar to predicates (e.g., 200-250 seconds) | 250 |
| Color stability | YES (consistent with predicates) | YES |
| Biocompatibility | Must meet ISO 10993-1 and ISO 7405 standards | Biocompatible |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
The document does not specify sample sizes for the physical property bench tests. It states, "In-vitro bench tests were performed on the R&D Series Nova Compo N light cure nano hybrid composite according to the requirements in ISO 4049: 2009 (Dentistry - Polymer-based restorative)." ISO standards typically specify minimum sample sizes for various tests, but these specific numbers are not detailed in the summary.
- Sample Size for Test Set: Not explicitly stated for individual tests.
- Data Provenance: The studies are in-vitro bench tests and biocompatibility tests. No mention of human patient data (retrospective or prospective) for performance evaluation. The submitting company is IMICRYL DIS MALZEMELERI SANAYI VE TICARET A.S. from Turkey, so it can be inferred the testing was conducted under their purview, likely in Turkey or by an accredited lab.
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)
This is not applicable as the studies are primarily in-vitro bench tests and biocompatibility tests. "Ground truth" in the clinical sense (e.g., expert consensus on medical images or pathology reports) is not required or established for this type of device and testing. The ground truth for these tests comes from the established physical and chemical properties as measured by standardized laboratory methods.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This is not applicable for the in-vitro bench tests and biocompatibility studies described. Adjudication methods are typically employed in clinical studies or studies involving human interpretation of data (e.g., medical imaging) to resolve discrepancies.
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
This is not applicable. The device is a dental composite material, not an AI-powered diagnostic or assistive tool. Therefore, MRMC studies are not relevant nor were they conducted.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
This is not applicable. The device is a dental composite material, not a software algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
For the physical properties, the "ground truth" is established by standardized laboratory measurements according to ISO 4049:2009. For biocompatibility, the "ground truth" is established by laboratory tests according to ISO 10993-1 and ISO 7405, which determine the biological response (e.g., cytotoxicity, sensitization). There is no "expert consensus" or "pathology" in the medical diagnostic sense for these tests.
8. The sample size for the training set
This is not applicable. Since this device is a physical material (dental composite) and not an AI algorithm, there is no "training set."
9. How the ground truth for the training set was established
This is not applicable as there is no "training set" for a physical dental composite device.

IMIX PanoRad and PanoRad SL X-Ray Systems are indicated for use in generating radiographic images of human anatomy. They have Solid State X-ray Imaging systems intended to replace radiographic film/screen systems in all general-purpose diagnostic procedures. (Not for mammography.)
The modified device can produce digital x-ray images in various configurations.
The provided text is a 510(k) summary for the IMIX ADR Finland OY PanoRad and PanoRad SL Systems. This document aims to demonstrate substantial equivalence to previously cleared devices, rather than establishing acceptance criteria for a new, distinct device's performance.
Therefore, the document does not contain the information requested in your prompt regarding acceptance criteria, device performance studies, and ground truth establishment because it is focused on demonstrating that the revised device is substantially equivalent to existing, legally marketed devices.
Here's why each of your requested points is not present in the provided text:
- A table of acceptance criteria and the reported device performance: This document doesn't define new performance criteria or report performance against them. Instead, it compares the characteristics of the modified device to a predicate device to show they are essentially the same.
- Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): No specific test sets or clinical studies for performance evaluation are described. The filing relies on the established safety and effectiveness of the existing predicate devices and the individual components.
- 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): Since no new performance studies are detailed, there's no mention of experts establishing ground truth.
- Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable, as there's no new test set 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: This is not an AI/CAD device. It's an X-ray imaging system, so MRMC studies, especially with AI assistance, are not relevant to this filing.
- If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable, as this is a hardware device (X-ray system), not an algorithm.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable, as there's no new performance study requiring ground truth.
- The sample size for the training set: Not applicable, as this is not an AI/Machine Learning device that requires a training set.
- How the ground truth for the training set was established: Not applicable for the same reason as point 8.
In summary, the provided document focuses on demonstrating substantial equivalence of a modified X-ray system to a predicate device by comparing technical specifications and intended use, rather than presenting a de novo performance study with specific acceptance criteria and ground truth validation.

IMIX PanoRad and SomaRad X-Ray Systems are indicated for use in generating radiographic images of human anatomy. It has a Solid State X-ray Imaging system intended to replace radiographic film/screen systems in all general-purpose diagnostic procedures. (Not for mammography.)
The PanoRad consists of: A high resolution CCD detector with 14" x 17" or 17" x 17" image area. An X-Ray Tube & Collimator. A fully motorized positioned. A 65 kW high frequency generator. A 4 way floating table. An Image Acquisition workstation with DICOM 3 compliance.
The SomaRad consists of: A high resolution CCD detector with 14" x 17" or 17" x 17" image area. An X-Ray Tube & Collimator. A fully motorized positioned. A 50 kW high frequency generator. A table. An Image Acquisition workstation with DICOM 3 compliance.
The provided text describes a 510(k) summary for the IMIX PanoRad and SomaRad X-Ray Systems (K101435). This document focuses on demonstrating substantial equivalence to predicate devices rather than proving a device meets specific performance acceptance criteria through a clinical study.
Therefore, many of the requested elements for a study proving acceptance criteria (like sample size for test set, number of experts for ground truth, adjudication method, MRMC study, sample size for training set, how training set ground truth was established, and specific quantifiable acceptance criteria) are not applicable in this context. The document's purpose is to show that the new device is as safe and effective as previously cleared devices by comparing technical specifications and intended use.
Here's a breakdown of the available information:
Acceptance Criteria and Reported Device Performance
The concept of "acceptance criteria" in this 510(k) is primarily based on substantial equivalence to predicate devices. The device "meets acceptance criteria" if it is determined to be as safe and effective as the predicate devices, with no new indications for use or significant technological differences that would raise new questions of safety or effectiveness.

Study Information (Based on the provided text)
-
Sample size used for the test set and the data provenance:
- The document mentions "user (clinical image pairs)" as part of the testing data. However, it does not specify the sample size (number of images or patients) used for this "user" testing.
- The data provenance (country of origin, retrospective/prospective) is not explicitly stated.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided in the document. The "user (clinical image pairs)" testing implies some form of review, but the details of who performed this review, their number, or qualifications are absent. Given it's a 510(k) for an X-ray system rather than an AI diagnostic device, formal ground truth establishment by multiple experts is less common.
-
Adjudication method (e.g., 2+1, 3+1, none) for the test set:
- This information is 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:
- No MRMC study was done or mentioned. This document is for an X-ray imaging system, not an AI-assisted diagnostic tool. Its purpose is to demonstrate the safety and effectiveness of the hardware and software for image acquisition, primarily through comparison with predicate devices' technical specifications.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This is an X-ray system, not a standalone algorithm for diagnosis. The "standalone" performance here refers to the system's ability to produce diagnostic quality images, which is addressed by a combination of bench testing, user testing, and adherence to standards.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The term "ground truth" in the context of an X-ray system's performance is typically less about definitive diagnostic labels (like pathology) and more about the diagnostic quality of the images produced and their ability to aid in general diagnostic procedures. The "user (clinical image pairs)" testing likely involved qualitative assessment of image quality for diagnostic purposes, relative to the predicate devices. However, the specific type of ground truth (e.g., clinical interpretation, comparison to established standards for image quality) is not detailed.
-
The sample size for the training set:
- Not applicable. This is not an AI algorithm trained on a dataset in the way a diagnostic AI would be. The device's software is "identical to K070618" (a DICOM Pacs device), indicating it's a pre-existing software component rather than one developed through machine learning.
-
How the ground truth for the training set was established:
- Not applicable for the same reasons as above.
Summary of the Study and Conclusion:
The "study" or evaluation performed for the IMIX PanoRad and SomaRad X-Ray Systems was a substantial equivalence comparison. This involved:
- Bench testing: Evaluating the technical specifications and performance of the components.
- User testing (clinical image pairs): Likely qualitative assessment of image quality in a clinical setting by users. The details of this testing (sample size, expert involvement, ground truth, adjudication) are not provided.
- Standards testing: Ensuring compliance with relevant industry and safety standards (e.g., UL listed).
The conclusion was that the device is "as safe and effective as the predicate devices, have few technological differences, and have no new indications for use," thereby establishing substantial equivalence. This is a regulatory pathway, not a clinical trial designed to quantify performance against a specific clinical acceptance criterion.
