The full Chinese name of edr in cr is

The full Chinese name of edr in cr is exposure data identifier.

Exposure Data Recognizer (EDR) technology is a digital imaging technology that is the culmination of many years of experience in computed diagnostic radiology (CR). This technology automatically adjusts image density and contrast.

For overexposure or underexposure caused by inappropriate X-ray exposure conditions within a certain range, the CR system can also adjust to obtain images with ideal density and contrast. The device that realizes this function is exposure data. Recognizer (EDR).

EDR ??operates by taking advantage of the unique properties of X-ray image density and contrast in each imaging acquisition menu (imaging site and photography technique). EDR data comes from IP and imaging menus, in imaging segmentation Once the pattern and exposure field range are identified, a density histogram is derived for each image.

CR

CR is the English abbreviation of computed radiography. CR is a type of medical imaging disease diagnosis. It uses digital images to facilitate access to the PACS system, and can be combined with computer technology to process images to improve image quality. CR is relatively cheap, and one set of CR can digitize the entire hospital’s X-ray equipment.

CR can be translated as computerized X-ray photography, or digital X-ray photography. The digitization of CR replaces film and intensifying screens with an imaging plate (IP plate) that can be read repeatedly. After exposure, a latent image is generated on the IP board. The IP board is placed in the CR scanner, the IP board is scanned with a laser beam, the information is read, and a digital image is generated after analog/digital conversion.
