What is the meaning of DR value?

DR refers to a new digital X-ray photography technology directly controlled by computer, that is, X-ray information penetrating human body is converted into digital signals by using amorphous silicon flat panel detector, and images are reconstructed by computer and a series of image post-processing.

DR system mainly includes X-ray generator, direct conversion flat panel detector, system controller, image monitor and image processing workstation. Because of digital technology, DR performs various image post-processing according to clinical needs, such as automatic image processing technology, edge enhancement and sharpness technology, zoom roaming, image mosaic, area and density measurement and other rich functions.

Characteristics and advantages of DR imaging

1 and DR have fast imaging speed, the acquisition time is less than 10ms, and the imaging time is only 3 seconds. The radiologist immediately observes the image on the screen.

2. The direct conversion technology of 2.DR simplifies the network work with high efficiency, paving the way for medical images to be fully digital and filmless.

3. Effectively solve the problem of image archiving management and transmission, save image data in the form of CD burning, and provide photo printing service for candidates at any time to prevent photos from being lost and repeated. Moreover, the high-definition DR photos are mutually recognized by the major hospitals in the whole region, and there is no need to repeat the inspection in the superior hospital, which reduces the cost of repeated inspection.
