Study Details:
-
Sample size used for the test set and the data provenance:
- The document does not specify a sample size for image data or specific cases used in performance testing.
- The testing performed was on the device itself as product, not on a dataset of patient images.
- Data Provenance: Not applicable in the context of image data. The device itself is manufactured by NEC Display Solutions Ltd. in Japan.
-
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- This information is not provided. The study focuses on technical performance of the monitor, not diagnostic accuracy based on expert interpretation of images displayed on it. The "trained physicians" are mentioned in the intended use, but not as part of the performance testing methodology.
-
Adjudication method for the test set:
- This information is not provided and is not directly relevant for the type of device (display monitor). The performance testing described refers to meeting technical criteria from AAPM Task Group 18, which would typically involve objective measurements rather than expert adjudication of clinical findings.
-
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, an MRMC comparative effectiveness study was not done. This device is a display monitor, not an AI diagnostic algorithm.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- No, this is not an algorithm. The performance testing was for the monitor itself.
-
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- The "ground truth" for this device's performance is based on the specifications outlined in the AAPM Task Group 18 report ("Assessment of Display Performance for Medical Imaging Systems"). These are objective, measurable technical specifications (e.g., brightness, contrast, resolution, gray scale accuracy) rather than clinical diagnostic ground truth. The study states "The results showed that all the testing items met the criteria."
-
The sample size for the training set:
- Not applicable. This is a hardware device (monitor), not an AI algorithm requiring a training set.
-
How the ground truth for the training set was established:
- Not applicable. This is a hardware device (monitor).

Dear Mr. Devine:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into class II (Special Controls), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of

medical device-related adverse events) (21 CFR 803); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Parts 801 and 809), please contact the Office of In Vitro Diagnostic Device Evaluation and Safety at (301) 796-5450. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

§ 892.2050 Medical image management and processing system.
(a)
Identification. A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.(b)
