The working principle of the X-ray image intensifier is realized by using the principles of physical electronics and optics.
In short, the image formed by X-rays penetrating the illuminated object is projected to the image receiving end of the intensifier, so that the receiving end of the intensifier is excited to produce a weak visible light image. This image-generating light excites the photocathode to generate escaped electrons, and the generated electrons are accelerated and focused to the image output of the intensifier under the action of a high-voltage electric field. Under the dual action of electrons and accelerated convergence, the fluorescent screen at the image output of the exciter is excited to produce a visible light image with sufficient brightness. The brightness of the image produced by the output screen is enough to make the electronic camera sensitive, thus realizing the conversion of X-ray signal→visible light signal→electrical signal. Electronic images converted to light signals can be arbitrarily processed by cameras and then transmitted further afield to be viewed on monitors, which also isolates humans from machines and keeps operators away from radiation. At the same time, due to the electron acceleration excitation principle of the intensifier, the brightness of the image can be further improved, thereby greatly reducing the radiation dose of the subject, thereby achieving the purpose of reducing radiation damage.
