Introduction to DR system

The DR system, that is, the direct digital X-ray photography system, is composed of an electronic cassette, a scanning controller, a system controller, an image monitor, etc. It directly converts X-ray photons into digital images through the electronic cassette. Image is a direct digital X-ray photography in a broad sense. In the narrow sense, direct digital photography is DDR (DirectDigit Radiography), which usually refers to digital radiography using the direct image conversion technology of flat-panel detectors. It is a direct digital X-ray photography system in the true sense.

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 DR and column (UC arm) DR;
