ABSTRACT:
A dental x-ray diagnostics installation for generating panorama tomograms of a patient has a rotary unit on which a radiation source and a carrier for a film cassette are mounted. The rotary unit is mounted so as to be rotatable around a vertical axis and can also be swivelled at right angles relative to the axis of symmetry of the patient while simultaneously undergoing rotational motion. The mount for the film cassette can be adjusted relative to the radiation source independently of adjustment of the rotary unit. A control unit operates the rotary unit so that, proceeding from an initial position, the rotary unit is repeatedly rotated by a selected angle corresponding to a desired area to be examined, and further controls the drive for the film cassette at a speed corresponding to a selected tomogram position upon each repeated transillumination of the subject.
