An x-ray radiator has an x-ray tube disposed in a protective housing and a fastening means having a portion attached to the x-ray tube inside the housing, and a portion which extends through the housing to the exterior of the housing. The exterior portion serves as a fastener to attach the x-ray radiator to a mount. The x-ray tube, within the housing, thus becomes directly attached to the exterior mount, which improves the precision with which the specified position of the central ray of the x-ray beam emanating from the x-ray tube can be achieved.

X-ray radiator having an externally accessible fastening means

A half-wave rectifier is connected between the cathode-side end of the secondary winding of the high voltage transformer and the x-ray tube anode. Between the anode and the anode-side end of the high voltage secondary winding, a high voltage capacitor is connected, which is capable of storing a portion of the energy necessary in order to feed the x-ray tube during one mains half wave. The rectifier is polarized such that the capacitor is charged during those particular secondary half waves in which current does not flow through the x-ray tube.

X-ray diagnostic generator

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.
