ABSTRACT:
A dental X-ray diagnostic installation in which an X-ray tube has an X-ray image intensifier associated therewith, and that means are provided which permit an alignment of its inlet screen with the focus of the X-ray tube. The X-ray image intensifier, during the carrying out of radioscopies, receives the X-radiation emanating from the patient and amplifies the radiation. Accordingly, it thereby permits the observation of the presently produced X-ray image either directly through an optical device associated with its outlet screen, or indirectly through the intermediary of a video system connected to the output thereof.
