What does doctor mean?

Dr is the abbreviation of English digital radiography, which means digital X-ray photography. This is a new technology.

1, 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.

2.DR technology has wide dynamic range, high X-ray quantum detection efficiency (DQE) and wide exposure range. Even if the exposure conditions are slightly worse, a good image can be obtained. The appearance of DR broke the traditional concept of X-ray image and realized the transformation from analog X-ray image to digital X-ray image that people dreamed of.

3. The 3.DR system has changed the traditional photography and imaging methods, and the time resolution has been obviously improved. Digital images can be obtained within 10 second after exposure, which greatly improves the work efficiency, and can be used to check all parts of the body, which greatly facilitates the diagnosis and treatment of clinical acute and severe patients.

4.DR system effectively solves the problem of image archiving management and transmission, saves image data in the form of CD burning, and can provide photo printing service for the examinee at any time to prevent the loss and repetition of photos. 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.
