Nine-inch image intensifier

The image intensifier (nine-inch image intensifier) ​​is no stranger to most hospitals and dealers. Many dealers and hospitals ask if the image intensifier is damaged, whether it can be repaired. The answer is yes, it can be fixed. There are many reasons for damage to the image intensifier. This requires testing, because the cost of replacing the image intensifier is too high, and the damaged image intensifier has been repaired first, and if the maintenance is not good, you can only buy a new one.
First, let us talk about the working principle of the image intensifier (nine-inch image intensifier): When X-rays pass through the human body, according to the different densities of human tissues, X-rays of different intensities will be projected onto the input screen. The photocathode inside the phosphor 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 electrode at high speed, and the photoelectrons are projected through the anode hole on the output screen to produce a visible image, which is brighter and smaller than the cathode. The previous perspective.
The nominal incident field size of the 9-inch image intensifier is 230mm. It is mainly used for C-arms, multifunctional gastrointestinal machines, digital machines, lithotripters and industrial inspection X-ray machines. It consists of an X-ray image multiplier consisting of a tube, a tube container, a special high-voltage power supply built in the tube container, and a low-voltage power supply for driving the high-voltage power supply.
