Digital X-ray photography is also a new digital imaging technology recently developed. It has similar uses to computer X-ray photography, 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.

Development history:

DR system after 1998 belongs to "direct digital" imaging system. The key component is the flat panel detector. It consists of a large number of small components with electronic coupling performance, which converts the received X-ray signals into corresponding electrical signals, and then converts them into digital signals and feeds them into the computer.

In the next step, DR system will replace the image intensifier tube _ TV chain to make DSA information acquisition equipment. The CT system made of flat panel detector instead of CT detector has been tested by prototype. Development prospect DR is mainly used to cooperate with the traditional X-ray machine to realize the digitization of plain film information due to its own characteristics.

It can be used for X-ray plain film display, and can also be used for comparative examination of gastrointestinal system, other systems and blood vessels. However, CR and DR are complementary imaging methods to replace conventional X-ray photography for a long time because they cannot be matched with multiple X-ray machines.
