  • Patent number: 6169780
    Abstract: An X-ray device for generating a panoramic tomogram is designed so that a revolving arm can move between a first position, where an X-ray generator and an X-ray receiver that are both supported by the revolving arm oppose each other through the head of a patient positioned in a patient positioning station, and a second position, where an operator of the X-ray device can look at the patient's head from a side view, thereby allowing the operator to properly position the patient in the patient positioning station. The incorporation of a second X-ray receiver additionally allows for the generation of a cephalogram. The incorporation of a blind prevents the patient from visually or physically interacting with selected components of the apparatus.
