2. Sample Size Used for the Test Set and Data Provenance
The document explicitly states: "No animal or clinical testing is needed for C81W+." This means there was no "test set" of patient data in the traditional sense involving medical images for diagnostic performance evaluation. The "test set" here refers to the device itself undergoing various technical bench tests.
- Test Set Sample Size: N/A (as it refers to the device undergoing technical tests, not a dataset of medical images).
- Data Provenance: The data comes from bench testing performed on the C81W+ device, following guidelines like AAPM TG18. The country of origin for the device manufacturer is Shenzhen, China. The testing itself is implied to be conducted by or for Shenzhen Beacon Display Technology Co., Ltd.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Since no clinical or retrospective patient data was used, there were no experts establishing "ground truth" for a medical image test set in this context. The "ground truth" for the device's technical specifications is established by internationally recognized standards (like DICOM GSDF, AAPM TG18 guideline) and the specifications of the legally marketed predicate device. The experts involved would be engineers or technicians with expertise in display technology and medical imaging standards, who conducted the bench tests and validated conformance. Their specific number and qualifications are not detailed in this premarket notification.
4. Adjudication Method for the Test Set
Not applicable. There was no clinical test set requiring adjudication by medical experts.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not performed. The submission explicitly states "No animal or clinical testing is needed for C81W+." This type of study would involve human readers evaluating cases with and without AI (or in this case, a new display) and comparing their diagnostic performance.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Not applicable. The device is a display monitor, not an AI algorithm. Therefore, a "standalone algorithm performance" study is irrelevant here. The performance evaluated is the technical display characteristics.
7. The Type of Ground Truth Used
The "ground truth" for the device's performance is based on:
- Technical specifications derived from established standards (e.g., DICOM GSDF, AAPM TG18).
- Performance data of a legally marketed predicate device (EIZO RadiForce RX850).
- Physical measurements obtained during bench testing of the C81W+ device.
8. The Sample Size for the Training Set
Not applicable. This device is a display monitor, not a machine learning or AI algorithm, so there is no "training set."
9. How the Ground Truth for the Training Set Was Established
Not applicable. As there is no training set for an AI algorithm, there is no ground truth to be established for it.

8.3 Performance Testing
According to the instructions in Guidance for Industry and FDA Staff: Display Accessories for Full-Field Digital Mammography Systems-Premarket Notification (510(k)) Submissions, the bench tests were performed on C81W+ as below.
- Verify the conformance to DICOM GSDF in accordance with Assessment of Display Performance for Medical Imaging Systems by AAPM Task Group 18 (TG18 guideline).
- Measure the angle dependency of luminance response in horizontal, vertical and diaqonal directions.
- Measure the luminance non-uniformity characteristics of the display screen in accordance with TG18 quideline.
- Measure the chromaticity non-uniformity characteristics of the display screen in accordance with TG18 guideline.
- Measure the chromaticity at the center of the display screen at 5%, 50% and 95% of the maximum luminance.
- Measure the display reflections including specular, diffuse and haze components.
- Measure the small-spot contrast ratio.
- Measure the spatial resolution expressed as modulation transfer function (MTF).
- Measure the noise expressed as noise power spectrum (NPS).
- Measure the pixel aperture ratio.
- Visually check the presence or absence of miscellaneous artifacts on the display screen in accordance with TG18 guideline.
- Measure the temporal response.
- The performance data on luminance stability
- Maximum number allowed for each type of pixel defects/faults
The test results showed that C81W+ is with display characteristics equivalent to those of the predicate device, RadiForce RX850 except some items, each of which was determined that it would not affect observer's performance.

(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)
