Digital plate detector

Digital plate detector is the core of DR technology, which is mainly composed of protective layer (shell), fluorescent layer, circuit board and radiator.Working principle of digital flat panel detector is located in the probe on the surface of the attenuation of X-ray scintillator will through the human body after converted to visible light, under the scintillation of amorphous silicon photodiode array and visible light is converted to electrical signals, the capacitance of the photodiode itself form the storage charge, storage charge of each pixel is proportional to the incident X-ray intensity, under the action of control circuit, scan read each pixel storage charge, output digital signal after A/D conversion, transmitted to the computer image processing to form X-ray digital image.
