The document describes a medical monitor for displaying images and details performance testing related to display characteristics, not image analysis or processing using AI/ML. There is no mention of AI, ML, or related concepts.
No.
This device is a medical monitor used for displaying radiological images for review and diagnosis, not for providing therapy.
Yes
The "Intended Use / Indications for Use" states that the device is "indicated for use in displaying radiological images...for review, and diagnosis by trained medical practitioners." This explicitly identifies its role in diagnosis.
No
The device is described as a "Medical Monitor" and the performance studies include testing of hardware characteristics like spatial resolution, luminance, and electrical safety, indicating it is a physical display device, not software only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD devices are used to examine specimens derived from the human body. The intended use and device description clearly state that this device is a medical monitor used for displaying and reviewing radiological images. These images are generated from the human body, but the monitor itself is not analyzing a biological specimen.
- The device's function is displaying images for diagnosis. While the images are used for diagnosis, the monitor's role is to present the visual information, not to perform a diagnostic test on a sample.
The information provided describes a medical imaging display device, which falls under a different regulatory category than IVD devices.

Performance Items Tested:
a. Spatial resolution: Measurements of the transfer of information from the image data to the luminance fields at different spatial frequencies of interest typically done by reporting the modulation transfer function. Non-isotropic resolution properties should be characterized properly by providing two-dimensional measurements or measurements along at least two representative axes.
- SE Note: As demonstrated through the function of the resolution for the TG18 test pattern and the comparison of MTF measurements, the specification of the proposed device is equivalent to the predicate device.
b. Pixel defects: Measurements (count, types (e.g., sub-pixel or entire pixel, always-on, always-off), and locations (map) of pixel defects. This is typically provided as a tolerance limit. Pixel defects can interfere with the visibility of small details in medical images.
- SE Note: As demonstrated through the measurements of the pixel defects, the specification of the proposed device is an equivalent predicate device.
c. Artifacts: Evaluate for image artifacts such as ghosting and/or image sticking from displaying a fixed test pattern for a period of time.

d. Temporal response: Measurements of the temporal behavior of the display in responding to changes in image values from frame to frame. Since these transitions are typically not symmetric, rise and fall time constants are needed to characterize the system. Slow displays can alter details and contrast of the image when large image stacks are browsed or in video, panning, and zooming modes.

j. Spatial noise: Measurements of the spatial noise level as represented by the noise power spectrum using an appropriate ratio of camera and display pixels. Spatial noise and resolution affect the way images are presented to the viewer and can alter features that are relevant to the interpretation process of the physician or radiologist.
- SE Note: Demonstrated through the function of the noise levels for the TG18 test pattern and recommended luminance values analysis, the specification of the proposed device is equivalence to that of the predicate device.
k. Reflection coefficient: Measurements of the reflection coefficients of the display device. Specular and diffuse reflection coefficients can be used as surrogates for the full bidirectional reflection distribution function.
- SE Note: As demonstrated through the measurements of the reflection Coefficient (Rd), the specification of the proposed device is equivalent predicate device.
l. Veiling glare or small-spot contrast: Measurements of the contrast obtained for small targets.

| uniformity of the luminance | |||
| across the display screen. | As demonstrated through the | ||
| measurements of the | |||
| uniformity of the luminance | |||
| across the display screen, | |||
| the specification of the | |||
| proposed device is an | |||
| equivalence predicate device. | |||
| i. | Stability of luminance and | ||
| chromaticity response | |||
| with temperature and time | Measurements of the change | ||
| in luminance and | |||
| chromaticity response with | |||
| temperature and use time. | As demonstrated through the | ||
| measurements, there is no | |||
| display off, and the user can | |||
| see the display without | |||
| Measurements | Description | SE Note | |
| temperature on use time; the | |||
| specification of the proposed | |||
| device is an equivalence | |||
| predicate device. | |||
| j. | Spatial noise | Measurements of the spatial | |
| noise level as represented by | |||
| the noise power spectrum | |||
| using an appropriate ratio of | |||
| camera and display pixels. | |||
| Spatial noise and resolution | |||
| affect the way images are | |||
| presented to the viewer and | |||
| can alter features that are | |||
| relevant to the interpretation | |||
| process of the physician or | |||
| radiologist. | Demonstrated through the | ||
| function of the noise levels | |||
| for the TG18 test pattern and | |||
| recommended luminance | |||
| values analysis, the | |||
| specification of the proposed | |||
| device is equivalence to that | |||
| of the predicate device. | |||
| k. | Reflection coefficient | Measurements of the | |
| reflection coefficients of the | |||
| display device. Specular and | |||
| diffuse reflection coefficients | |||
| can be used as surrogates | |||
| for the full bidirectional | |||
| reflection distribution | |||
| function. | As demonstrated through the | ||
| measurements of the | |||
| reflection Coefficient (Rd), | |||
| the specification of the | |||
| proposed device is equivalent | |||
| predicate device. | |||
| l. | Veiling glare or small-spot | ||
| contrast | Measurements of the | ||
| contrast obtained for small | |||
| targets. | Demonstrated through the | ||
| function of the contrast | |||
| obtained for the TG18 test | |||
| pattern and recommended | |||
| luminance values analysis, | |||
| the specification of the | |||
| proposed device is | |||
| equivalence to that of the | |||
| predicate device. | |||
| m. | Color tracking | Chromaticity at different | |
| luminance levels of primary | |||
| colors as indicated by the | |||
| color coordinates in an | |||
| appropriate units system | |||
| (e.g., CIE u'v') and the color | |||
| gamut enveloped by the | |||
| primary colors. | As demonstrated through the | ||
| measurements of the sRGB | |||
| xy coverage, the specification | |||
| of the proposed device is | |||
| equivalent to that of the | |||
| predicate device. | |||
| n. | Gray tracking | Chromaticity at different | |
| luminance levels of gray | |||
| shades, including the white | |||
| point, as indicated by the | |||
| color coordinates in an | |||
| appropriate units system | As demonstrated through the | ||
| measurements of the sRGB | |||
| UV coverage, the | |||
| specification of the proposed | |||
| device is equivalent to that of | |||
| the predicate device. |
According to the quidance, we test following performance items:
