Recently, we received a customer consultation about our flat panel detector. Flat panel detector is usually divided into direct flat panel detector and indirect flat panel detector. Flat panel detector is divided into wireless and wired. Wireless flat panel detector mainly relies on WiFi to connect computer.
Direct conversion flat panel detector is mainly composed of amorphous selenium and thin film semiconductor array. Because amorphous selenium is a photoconductive material, the electron hole pair is formed directly after X-ray exposure to generate electrical signals. The digital image is obtained by TFT detection array and a / D conversion. Because amorphous selenium does not produce visible light and has no effect of scattered light, it can obtain relatively high spatial resolution.
