Since their inception in 1969, charge coupled devices (CCDs) have grown in use. CCDs expanded into digital cameras, telescopes, video cameras, scanners, and other imaging applications.
At present, most portable digital X-ray imaging systems are orthoptic type, they cannot export video frequency signal, test quantificationally and analyze with computer straightly.
