The working principle of the X-ray image intensifier is realized by using the principles of physical electronics and optics. Simply put, the image formed by X-rays penetrating the illuminated object is projected to the image receiving end of the image intensifier, thereby exciting the receiving end of the image intensifier to produce a weak visible light image. The light generated by this image in turn excites the photocathode to generate escaped electrons, and the generated electrons are accelerated and focused to the image output end of the image intensifier under the action of the high-voltage electric field. Under the dual action of electrons and accelerated convergence, the phosphor screen of the image output end of the image intensifier is excited to produce a visible light image with sufficient brightness. The brightness of the image generated by the output screen is enough to make the electronic camera sensitive, so as to realize the conversion of X-ray signal → visible light signal → electrical signal. The electronic image converted into an optical signal can be arbitrarily processed by the camera and transmitted to a farther place for viewing with a monitor, which also realizes the isolation of man-machine and keeps the operator away from radiation. At the same time, due to the principle of electronic acceleration excitation of the image intensifier, the brightness of the image can be further enhanced, and thus the radiation dose of the subject can be greatly reduced, so that the purpose of reducing radiation damage is achieved.
