Summary:PHD 80033 12.2.81 Dental tomography apparatus. A dental tomography apparatus comprises three drive motors for displacing the film and the X-ray source in two mutually perpendicular directions in a horizontal plane and for pivoting the carrier which connects the film and the X-ray source. The control signals for the motor drives are derived from the contour of the dentition by means of a plate which is covered by contacts on which the patient exerts a pressure by biting, so that the contacts whose position corresponds to the shape of the dentition are actuated. Therefrom, the contour of the dentition is determined by an arithmetic unit which supplies the control signals for the drive motors.
