What is the image contrast of the image intensifier

What is the image contrast of the image intensifier? What important effect does the image contrast of the image intensifier have on the image intensifier?
There is an image intensifier image contrast in the technical parameters of the image intensifier. What is the image contrast of the image intensifier? What role does the image contrast of the image intensifier play in the TV system of the image intensifier?
The image contrast of the image intensifier is the maximum position of the 2mm-thick circular X-ray shielding lead plate equivalent to 10% of the effective area of the entrance surface of the image enhancer. The ratio of the brightness to the brightness of the shaded part of the wire board is called the image contrast.
Therefore, the greater the image contrast of the image intensifier, the better, and the greater the image contrast, the better the image effect of the image intensifier, and the quality of the image intensifier can be guaranteed. The image contrast of current image intensifiers is generally 6: 1, 12: 1, 15: 1 or higher.
