Radiographic/Tomographic Systems

Definition : Radiographic systems that can move the x-ray source and the film cassette in a coordinated way so that images of structures in the plane of diagnostic interest (i.e., tomographic images) remain in focus, while images in other planes become blurred. In most of these systems, the film and the x-ray tube move in parallel, straight lines in opposite directions. Radiographic/tomographic systems are mostly used for lung and chest studies, retrograde or intravenous pyelograms, and middle-ear studies, as well as for the diagnosis of cervical-spine pathology, arthritis, joint trauma, and tumors.
