This Medical Monitor is indicated for use in displaying radiological images for review, analysis, and diagnosis by trained medical practitioners. The display is not intended for mammography.
The Medical monitor is intended to provide high resolution color and grayscale medical imaging for PACS and Radiology system. This Medical Monitor is intended to be used by trained medical practitioners for displaying, reviewing, and analysis of medical images,
The provided document is a 510(k) summary for a medical monitor (21HQ513D) and does not detail the acceptance criteria and study proving device performance as would be expected for an AI/ML-driven medical device. This document primarily focuses on demonstrating substantial equivalence to a predicate device for regulatory clearance.
However, it does include a "Bench Test – Performance Test Report" which lists various measurements and their test results. While not a study proving the device meets AI/ML acceptance criteria, it demonstrates the physical display characteristics meet predefined criteria.
Here's an interpretation based only on the provided text, focusing on the nearest relevant information:
1. A table of acceptance criteria and the reported device performance
The document does not specify quantitative acceptance criteria for each measurement, but rather indicates a "Pass" or "N/A" for each as well as a general statement that "All display characteristics of the 21HQ513D have met the pre-defined criteria."
| Measurements | Test Result | Acceptance Criteria (Implied) |
|---|---|---|
| a. Spatial resolution | Pass | Met pre-defined criteria |
| b. Pixel defects | Pass | Met pre-defined criteria |
| c. Artifacts | Pass | Met pre-defined criteria |
| d. Temporal response | Pass | Met pre-defined criteria |
| e. Luminance | Pass | Met pre-defined criteria |
| f. Conformance to a grayscale-to-luminance function | Pass | Met pre-defined criteria |
| g. Luminance at 30° and 45° in diagonal, horizontal, and vertical directions at center and four corners | N/A | Not applicable/measured |
| h. Luminance uniformity or Mura test | N/A | Not applicable/measured |
| i. Stability of luminance and chromaticity response with temperature and time of operation (on-time) | N/A | Not applicable/measured |
| j. Spatial noise | N/A | Not applicable/measured |
| k. Reflection coefficient | N/A | Not applicable/measured |
| l. Veiling glare or small-spot contrast | N/A | Not applicable/measured |
| m. Color tracking | Pass | Met pre-defined criteria |
| n. Gray tracking | Pass | Met pre-defined criteria |
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
This information is not provided in the document. The tests appear to be bench tests conducted on the device itself, rather than studies involving medical images or patient 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 information is not provided in the document. The tests seem to be objective measurements based on established standards (e.g., "FDA guidance 'Display Devices for Diagnostic Radiology'").
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
This information is not provided in the document.
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 such study was performed or described. The device is a medical monitor, not an AI-driven diagnostic aid. The document explicitly states: "No clinical studies were considered necessary and performed."
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. The device is a monitor, not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
Not applicable. The performance tests are based on physical characteristics and compliance with industry standards and FDA guidance for display devices, not on medical ground truth.
8. The sample size for the training set
Not applicable. This device is a medical monitor, not an AI/ML diagnostic algorithm that requires a training set.
9. How the ground truth for the training set was established
Not applicable.

Dear Daseul An:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. 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.

§ 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)
