DR system, namely direct digital X-ray photography system, is composed of electronic cassette, scanning controller, system controller, image monitor, etc., which directly converts X-ray photons into digital images through electronic cassette, and is a kind of direct digital X-ray photography in a broad sense.In the narrow sense, direct digital photography, namely DDR, usually refers to digital Radiography with the technology of direct image conversion using flat panel detector, which is a direct digital X-ray photography system in the true sense.According to the detector type, it is mainly divided into amorphous silicon plate DR(main stream), amorphous selenium plate DR and CCD DR(main stream).According to the frame structure, it is divided into hanging DR and UC arm DR.
The NKX-502 Sickle-arm DR machine produced by Shandong Huarai Imaging is mainly used for the photographic examination of human chest, limbs, pelvis and lumbar spine.
1, microcomputer control, LIQUID crystal display, easy to operate.
2. New design of high frequency and high voltage generator
3. Stable and accurate exposure conditions can reduce the production of soft rays while reducing radiation dose, effectively protecting patients and doctors.
4, simple and convenient position display, according to the selection of patient body shape, location, automatic exposure parameters, and can be saved and modified.New sickle arm design
5. Accurate rotation Angle and multi-angle photography can meet clinical requirements.
6. Reassuring security features
Fault self-diagnosis function can quickly and accurately determine the fault status, and can automatically protect, display fault code, accurate and convenient in time.7. Adopting digital plate detector, the performance is stable and the X-ray dose is greatly reduced
