DICOM (Digital Imaging and Communication in Medicine)
The DICOM standard was developed by the American College of Radiology and the National Electrical Manufacturer’s Association of the USA.
The DICOM compatible device connection enables to transfer the medical image and information. The DICOM, Part 14 document denes the digital,
grayscale medical image display.
DisplayPort
This is the interface standard for image signals standardized in accordance with VESA. It was developed with the aim of replacing the conventional DVI
and analog interfaces, and it can transmit high resolution signals and sound signals, which DVI does not support. The standard size and mini size
connectors have been standardized.
DVI DMPM (DVI Digital Monitor Power Management)
DVI DMPM is a digital interface power saving function. The “Monitor ON (operating mode)” and “Active Off (power saving mode)” are indispensable for DVI
DMPM as the monitor’s power mode.
Gain
This is used to adjust each color parameter for red, green and blue. An LCD monitor displays the color by the light passing through the panel color lter.
Red, green and blue are the three primary colors. All the colors on the screen are displayed by combining these three colors. The color tone can be
changed by adjusting the light intensity (volume) passing through each color’s lter.
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called “Gamma Characteristic”. When the gamma value is low, the
middle tone area is displayed brighter, and darker when high. Changes to the gamma value will not affect contrast. A gamma value appropriate for the
display content should be selected.
