What does dr mean? What exactly does dr mean?

Digital Radiography (DR) is also a new digital imaging technology recently developed, which has similar uses to Computer Radiography (CR), but its basic principle and structure are different. DR is developed on the basis of digital fluorescence photography. It takes the image intensifier tube as the information carrier, receives the X-ray information transmitted through the human body, converts it into digital signals after being collected by the camera, and then carries out digital processing.

Different from CR, except the information carrier, it is not matched with other equipment and needs special equipment. CR can collect information through the imaging board on any X-ray imaging equipment. DR, like CR, can do post-processing of many kinds of images, and can transmit and store images.

Head, chest, limbs and other parts do not need special preparation; Gastrointestinal tract cleaning should be done well in photography of abdomen and its overlapping parts. Substances related to the photographic parts that affect the X-ray transmission, such as hairpins, metal ornaments, plasters and clothes that need to be replaced, should be removed.
