What does an image intensifier do?

Image intensifiers are not unfamiliar to most hospitals and dealers. Many dealers and hospitals have come to ask if the image intensifier can be repaired if it is broken. It can definitely be repaired. It is necessary to test, because the cost of replacing an image intensifier is too high now, and the bad ones are basically repaired first. Let’s talk about the working principle of the image intensifier first: when the X-ray passes through the human body, X-rays with different intensities are projected on the input screen according to the different densities of the human tissue, and the photocathode on the inside of the fluorescent screen is based on the intensity of the fluorescence. Different numbers of photoelectrons are generated. The photoelectrons of the photocathode are attracted by the positive potential of the anode and fly to the positive at high speed. The photoelectrons pass through the small holes of the anode and are projected on the output screen, producing a visible image, which is brighter than the previous fluoroscopic image. Zoom out.
