The general principle of DR flat panel detector: the X-ray is first converted to visible light by the fluorescent medium material, and then converted to electrical signal by the photosensitive element, and finally converted to digital signal by the analog electrical signal through AD.
1. Before exposure, make the silicon surface store cations to generate uniform charge, resulting in the formation of electron field on the silicon surface;2. During the exposure, electron hole pairs are generated in silicon, and free electrons are free to the surface, resulting in potential charge images on the silicon surface. The charge density at each point is equivalent to the local line intensity.
3. After exposure, the X-ray image is stored in each pixel;
4. The semiconductor converter reads each element to complete the analog-to-digital conversion.
