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 defines 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 (Digital Visual Interface)
DVI is a digital interface standard. DVI allows direct transmission of the PC's digital data without loss.
This adopts the TMDS transmission system and DVI connectors. There are two types of DVI connectors. One is a DVI-D connector for digital signal input
only. The other is a DVI-I connector for both digital and analog signal inputs.
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 filter.
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 filter.
Gamma
Generally, the monitor brightness varies nonlinearly with the input signal level, which is called "Gamma Characteristic". A small gamma value produces a
low-contrast image, while a large gamma value produces a highcontrast image.
