X-ray image intensifier is an image intensifier, which can reduce the radiation dose, and can keep the operator away from radiation, avoid X-ray radiation damage, and will reduce the large radiation damage to the subject’s human body.
The working principle of X ray image intensifier is realized by the principle of physical electronics and optics. In simple terms, the image formed by the X-ray penetrating the illuminated object is projected to the image receiving end of the intensifier, thereby exciting the receiving end of the X-ray image intensifier to produce a weak visible light image.
There are probably three main reasons for the occurrence of spots on the X ray image intensifier:
1. There is a lot of dust in the air in the room
2. The organic membrane material has impurities
3. Poor quality of deionized water
Of course, there are other possibilities.
