Patent ID: 7197109

Claim:
A dental x-ray diagnostic apparatus for performing real-time digital radiography in Cephalography of a patient skull, the apparatus comprising: a base frame arrangement; a rotary frame coupled to the base frame arrangement, the rotary frame supporting an x-ray source; a cinematic unit connecting the rotary frame and the base frame arrangement, the cinematic unit being configured to execute roto-translational movements of the rotary frame, wherein the roto-translational movements comprise one rotation movement and two transverse linear movements in a horizontal plane, and the roto-translational movements of the rotary frame being driven by independent actuators in the cinematic unit controlled by data supplied from a microcomputer; an x-ray imager disposed in a Cephalographic position, the x-ray imager being movable during a scanning operation by an independent actuator; and wherein the roto-translational movements of the cinematic unit permit the rotary frame to perform a roto-translating scanning trajectory to permit illumination of the patient skull by the x-ray source from a predefined virtual center of irradiation.
