Abstract
Panoramic dental X-ray machine possessing mechanical and electronic simplicity for providing both continuous and discontinuous radiographs of a dental arch area. The machine includes an excursion mechanism which causes a tubehead-camera assembly to uninterruptedly circularly orbit the patient's head at a constant speed. A drive mechanism is employed which controls the shifting or transport of the patient along an X-axis only, when either continuous or discontinuous images are desired. The kVp and milliamperes remain constant during the entire exposure of the patient to the X-rays as well as the rotational speed of the tubehead-camera assembly, and no attenuating members are required in the X-ray path for varying intensity of the X-ray beam.
