The image intensifier consists of a shell, an intensifier vacuum tube (including an intensifier input screen and an intensifier output screen), a high voltage power module and a high voltage cable.
X-ray is invisible, because of its physical characteristics, the initial use depends on X-ray sensitive compounds stimulated by it to produce fluorescence and achieve imaging purposes. Therefore, if the corresponding protection is not done properly, the operator will be damaged by X-ray radiation to varying degrees. At the same time, when used for human body examination, if the radiation dose is too large, it will also cause greater radiation damage to the human body of the subject. For this reason, people are actively looking for ways to reduce radiation dose and keep operators away from radiation. Therefore, X-ray image intensifier came into being.
