Digital dental imaging or digital dental image acquisition is the creation of digital dental images, typically from a physical object. The term is often assumed to imply or include the processing, compression, storage, printing, and display of such images.
A digital image may be created directly from a physical scene by a camera or similar device. Alternatively, it may be obtained from another image in an analog medium, such as photographs, photographic film, or printed paper, by a scanner or similar device. Many technical images—such as those acquired with tomographic equipment, side-looking radar, or radio telescopes—are actually obtained by complex processing of non-image data. Finally, digital dental imaging can also be computed from a geometric model or mathematical formula (however, in this case the name image synthesis is more appropriate). Dental imaging is used by dentists and dental technicans .
