The structure and principle of DR, DR is the abbreviation for digital radiographic. DR is based on the high frequency X ray machine, combined with flat panel detectors 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., which 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 panel DR (mainstream), amorphous selenium flat panel DR and CCD DR (mainstream); according to the frame structure, it is divided into suspension and column UC arms.
