How electronic images are generated through image intensifiers

The working principle of X-ray image intensifier (hereinafter referred to as intensifier) is realized by using physical electronic and optical principles. In simple terms, the image formed after the X-ray penetrates the illuminated object is projected onto the image receiving end of the intensifier, which excites the receiving end of the intensifier to generate a weak visible image. The light generated by this image also excites the photocathode to generate the escaped electrons, which are accelerated and focused to the image output end of the intensifier under the action of high voltage electric field. The fluorescent screen at the image output end of the intensifier is excited under the dual effects of electrons and acceleration convergence 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, thus realizing the conversion of X-ray signal – → visible light signal – → electrical signal. The electronic image converted into optical signal can be arbitrarily processed by the camera and transmitted to a far place to be viewed by the monitor, which also realizes the isolation of human and machine, and keeps the operator away from radiation. At the same time, due to the principle of electronic acceleration excitation of the intensifier, the image brightness can be further enhanced, and the radiation dose of the subject can be greatly reduced, which also achieves the purpose of reducing radiation damage.
