  • Patent number: 5033070
    Abstract: A panoramic method for the radiography of the dental arch and jaws, in which method by means of movable radiographing and/or imaged elements, several subsequent exposure sweep sequences are performed so that the moving elements are transferred to a new position betwen the subsequent exposure sequences. In order to achieve a perfectly jointed X-ray picture, the movement of the moving elements is started before the switch-on instant of the X-ray beam in the latter exposure sequence and the starting positions of said elements is selected so as to obtain desired positions and velocities for the elements at the switch-on instant of the X-ray beam. The coincidence of the X-ray beam orientation at the start of the latter exposure sequence with the X-ray beam orientation at the end of the preceding sequence is characterizing to an embodiment of the invention.
