Abstract

Abstract Translated from German Das Dental-Tomographiegerät besitzt drei Antriebsmotoren zur Verschiebung von Film und Röntgenstrahler in zwei voneinander senkrechten Richtungen in einer Horizontalebene und zur Schwenkung des Film und Röntgenstrahler verbindenden Tragarms. Die Steuersignale für die Motorantriebe werden aus der Gebißkontur abgeleitet, die mit Hilfe einer mit Kontakten besetzten Platte ermittelt werden, auf die der Patient beißt, so daß die Kontakte, deren Lage der Form des Gebisses entspricht, betätigt werden. Ein Rechner ermittelt daraus die Kontur des Gebisses und liefert Steuersignale für die Antriebsmotoren. The dental tomography device has three drive motors for displacing the film and the X-ray emitter in two mutually perpendicular directions in a horizontal plane and for pivoting the support arm connecting the film and the X-ray emitter. The control signals for the motor drives are derived from the contour of the dentition, which are determined with the aid of a plate with contacts on which the patient bites, so that the contacts, the position of which corresponds to the shape of the dentition, are actuated. A computer uses this to determine the contour of the bit and supplies control signals for the drive motors.
