Image intensifiers are not unfamiliar to most hospitals and dealers. Let me first talk about the working principle of image intensifiers. After X-rays pass through the human body, X-rays of different intensities are projected according to the different densities of human tissues. The photocathode on the inner side of the fluorescent screen generates different numbers of photoelectrons according to the intensity of the fluorescence. The photoelectrons of the photocathode are attracted by the positive potential of the anode and fly to the positive at high speed, and the photoelectrons pass through the small hole of the anode and are projected to the output screen , produces a visible image that is brighter and smaller in size than the previous fluoroscopic image.
Many people ask what is the role of the image intensifier? The image intensifier is an electronic device that converts X-ray images into visible light image output. It is installed on the X-ray TIV device for X-ray fluoroscopy and photography. Mainly used in fluoroscopy machines, etc., it is essential for hospitals. Therefore, if the image intensifier is broken, it is a very troublesome thing for the hospital.
