What is the meaning of dr, dr in the end refers to what?
Digital radiography is also the recent development of a new digital imaging technology, and computed radiography has a similar purpose, but the basic principles and structure are different.DR is based on the development of digital fluorescence photography, it is an image enhancement tube as a carrier of information, acceptance of X-ray information through the human body, captured by the video camera converted to digital signals, and then digitized.
In addition to the difference in information carriers, it does not match with other equipment and requires the use of specialized equipment, while CR can be used in any X-ray imaging equipment with an imaging plate to capture information. DR, like CR, can do a variety of post-processing of the image can be transmitted and stored images.
No special preparation is needed for the head, chest, limbs, etc.; for photography of the abdomen and areas overlapping the abdomen, the gastrointestinal tract should be cleaned. Substances associated with the photographic site that affect X-ray transmission, such as hairpins, metal jewelry, plasters, and clothing that needs to be changed, should be removed.
History:
DR systems that have appeared since 1998 are "direct digital" imaging systems. The key component is the flat panel detector. It consists of a large number of electronic coupling properties of the tiny components of the integrated plate, these small components were accepted by the X-ray signal is converted to the corresponding electrical signals, and then converted to digital signals fed into the computer.
DR system will be able to replace the next step in the image enhancement tube _ TV chain made of DSA information acquisition equipment; flat panel detector instead of CT detector made of CT system has been a prototype trial. Development prospects DR due to its own characteristics, mainly used and traditional X-ray machine to match, realize the digitalization of flat film information.
It can be used for X-ray flat film display, can also implement the gastrointestinal system, other systems and angiography, but because it can not be matched with more than one X-ray machine, so for a long time, CR and DR is to replace the conventional X-ray photography complementary imaging modality.
