Intended Use

JUSHA-M53 Medical Display is intended to be used in displaying and viewing digital images including those of digital mammography for review and analysis by trained medical practitioners.

Device Story

JUSHA-M53 is a 21.3-inch monochrome TFT LCD medical display (5MP resolution) used by radiologists/clinicians for viewing high-resolution medical images, including mammography. Input signals are received via DVI-D or DisplayPort from off-the-shelf display controllers. The device features an LED backlight, integrated front sensor for independent grayscale calibration, ambient light sensor for luminance adjustment, and presence sensor for power management. It supports 1024 simultaneous grayscale shades (12-bit LUT) compliant with DICOM Part 14. The display provides high luminance (1000 cd/m²) and wide viewing angles via IPS technology. Output is a visual representation of medical images, aiding clinicians in diagnostic review and analysis. The device is intended for clinical environments.

Clinical Evidence

Bench testing only. No clinical or animal studies were conducted. Performance was validated through measurements of angular luminance response, luminance/chromaticity non-uniformity (per TG18 guidelines), small-spot contrast ratio, temporal response, and luminance stability. Electrical safety and EMC testing confirmed compliance with IEC 60601-1 and IEC 60601-1-2.

JUSHA-M53 Medical Display is the display system with the high resolution (2560 x 2048) monitor (5 megapixels) with electronic capabilities for evaluation of high resolution medical images. It uses a monochrome LCD panel with IPS (in-plane switching) technology, so that it can

{6}------------------------------------------------

achieve wide viewing angles. JUSHA-M53 has a backlight sensor inside to stabilize the set luminance level automatically. JUSHA-M53 also has an integrated front sensor used for independent grayscale. With high luminance (1000 cd/m²) and 1024 simultaneous shades of gray out of a palette of 4096, 8 DICOM look up table with 12 bit, DSA, DSI and CT/MRI-JS curve which are calibrated in our factory are stored -inside the display.JUSHA-M53 has a ambient brightness sensor used to adjust the luminance and DICOM LUT along with the ambient brightness changing when the ambient function is enable. It has a brightening quickly button which can adjust the luminance and curve when press the button, this can be used to switch the using mode between high luminance and low luminance level, the is luminance used for diagnosis, the low luminance level is used for normal reading.JUSHA-M53 has an infrared sensor to detect whether there is a person in front of the display, it is working when there is a person, and it will be in power saving mode if there is no person in front of it. The JUSHA-M53 employs the same technology as its predicate devices K130336.
