What is CR System The CR system (computed radiography) is the use of a phosphor imaging plate to produce a digital image of X-rays. CR systems use cassettes containing analog film and are generally considered to be a link between old-fashioned radiography and the increasingly popular fully digital methods.

What is the working principle of CR system In CR systems, when the imaging plates are exposed to X-rays or gamma rays, the energy of the incoming radiation is stored on top of a special phosphor layer. There is a special machine, known as a scanner, which is used to read the hidden image from the plate by excitation with a very finely focused laser beam.

What is the process of CR system CR captures an analog image, which is digitized by the reader. As the image is read by the scanner, a focused laser releases the stored image in the form of visible light photons. These photons are collected and amplified by the scanner, converted into a digital signal and then transferred to a computer for processing and display.

what are the difference between DR system and CR system The difference between DR system and CR system is simply that – DR system is actually a digital X-ray whereas CR system is not an X-ray machine. DR uses flat panel detectors based on direct or indirect conversion to charge the system, which is then processed to form a digital image.

How does the CR Cassette work The CR system uses a cassette similar to a film cassette. It consists of an imaging plate similar to an intensive screen in a cassette instead of film. When X-rays interact with it to emit light, the imaging plate stores the X-ray energy in proportion and the intensity is obtained. When a CR system reader has a laser, the stored energy is released as visible light.
