We know that the image intensifier consists of an image multiplier tube, a tube container, a dedicated high voltage power supply built into the tube container, and a low voltage power supply that drives the high voltage power supply. So, do you understand how the image intensifier works?
The transmitted X-rays (X-ray images) that pass through the human body are illuminated onto the input screen of the image intensifier to obtain a fluorescent image with a weaker brightness, and then an image intensifier is obtained on the output screen. A fluorescent image that is reduced in size and is ten times brighter than the brightness on the input screen. After the fluorescent image on the output screen is transmitted and corrected by the optical system, it is taken by the camera tube. The video current signal output from the camera tube is amplified by the preamplifier, and the controller performs image signal control, processing and amplification to obtain a full TV signal. Go to the monitor and display the fluoroscopy image on the monitor screen.
