Digital flat panel detector

The digital flat panel detector is the core of the DR technology, which is mainly composed of a protective layer (housing), a fluorescent layer, a circuit board, and a heat sink. The working principle of the digital flat panel detector is that the scintillator on the surface of the detector converts the attenuated X-rays after passing through the human body into visible light, and the amorphous silicon photodiode array under the scintillator converts the visible light into electrical signals. The stored charge is formed on the capacitor of each pixel, and the stored charge of each pixel is proportional to the intensity of the incident X-ray. Under the action of the control circuit, the stored charge of each pixel is scanned and read, and the digital signal is output after A/D conversion, which is transmitted to The computer performs image processing to form X-ray digital images.
