The imaging principle of X-ray image intensifier

The X-ray image intensifier is composed of an input surface, a photocathode, a cluster electrode, an anode and an output surface in a vacuum.
After X-ray conversion, photoelectrons are accelerated by high voltage, and an image is formed on the output surface through an electron lens cluster composed of a cluster electrode and an anode.
A columnar crystal with a fiber structure is formed on the input surface, which can inhibit light diffusion and improve spatial frequency characteristics. The emitting surface can directly form a fluorescent film. In addition, the anti-reflection layer can be used to obtain high-contrast images.
In application, the emergence of image intensifiers allows radiologists to “liberate” from the darkroom. In the past, doctors had to wear red glasses for about five minutes of dark adaptation to observe the screen in complete darkness.
The image is clear and the contrast is good, which is helpful for finding lesions, improving work efficiency and diagnosis rate.
Newheek can also provide quality testing for your X-ray image intensifier.
