ABSTRACT:
An X-ray installation particularly adapted for dental diagnostic use wherein the radiating anode is disposed adjacent the remote end of a tube projecting from a cathode housing. The anode emitts radiation in substantially all directions and the tube has a length sufficient to be inserted into the patient's mouth. The tube containing the anode is equipped as desired with a radiation absorbing cap which in one instance limits radiation emission through a cap aperture for filming from within the patient's mouth and in a second instance comprises a slip-on cylindrical tube having a focusing opening at an axial end thereof for directing radiation to a specified area of the mouth from externally of the mouth.
