Abstract
An apparatus for positioning the head of a patient for producing dental panorama tomograms, which apparatus has an arrangement for positioning the head in a desired position relative to a fixed point with respect to at least one projection plane and this point, in turn, assumes a definite position relative to a central ray extending from the x-ray tube towards the x-ray picture, characterized by an arrangement for producing silhouettes and for projecting the silhouettes of the head in an actual position and in a desired position, simultaneously with the fixed point of each of the two silhouettes coinciding. By moving the head forming the silhouette of the actual position, the silhouette of the actual position can be moved to be congruent with the silhouette of the desired position to bring the head into the desired position for x-ray exposure.
