What is DR filming system, DR structure and principle?

The structure and principle of DR, DR is the abbreviation of digital photography, that is, the English name digital radiographic. DR is based on a high-frequency X-ray machine, combined with a flat panel detector and image acquisition and processing software. The DR system is a direct digital X-ray photography system, which is composed of a flat-panel detector, a scanning controller, an image monitor, etc., and converts X-ray photons into digital images through the flat-panel detector. In a broad sense, it can be called direct digital X-ray. photography. In a narrow sense, direct digital photography usually refers to digital radiography using the image direct conversion technology of flat panel detectors, which is a true direct digital X-ray photography system. According to the detector type, it is mainly divided into amorphous silicon flat DR (mainstream), amorphous selenium flat DR and CCD DR (mainstream); according to the frame structure, it is divided into suspension and column UC arms.
