In the digital camera, the conversion of X-ray energy into electrical signals is achieved by a flat panel detector, so the characteristics of the flat panel detector have a relatively large impact on the quality of the DR image. The choice of DR must take into account the choice of flat panel detectors. The performance indicators of flat panel detectors will have a great impact on the image, and the hospital should also choose the flat panel detector that suits its needs.
DR flat panel detectors can be divided into two types: amorphous selenium flat panel detectors and amorphous silicon flat panel detectors. From the perspective of energy conversion, the former belongs to the direct conversion flat panel detector, and the latter belongs to the indirect conversion flat panel detector.
