Universal indirect tomography.
The procedure is performed in two stages. First, during the radiographic exposure, the patient is rotated in relation to the X-ray tube and a recording device, namely a cinefluorographic device or a television chain with a video-recorder. In practice the tube and the recording device will be revolved around the patient. Later on, in the second stage, the cinefluorographic image, or the television image of the rotating patient, is projected onto a photographic film. If this film is adequately rotated, a tomographic picture will be produced. The method can be applied to conventional tomography, zonography, transverse tomography, autotomography and orthopantomography.
