ABSTRACT:
An x-ray tube construction comprising a housing and a shaft assembly mounted within the housing for rotational movement within the housing. An anode target is provided in the housing. A three-ball mounting is provided for mounting the anode target on the shaft assembly so that the anode target rotates with the shaft assembly. A cathode is disposed within the housing in the vicinity of the anode target. A voltage supply is connected to the anode target and to the cathode for accelerating electrons from the cathode to impinge upon the anode target to create x-rays. The three-ball mounting serves to minimize the transfer of heat from anode target to the shaft assembly. A motor drive is coupled to the shaft assembly for rotating the shaft assembly and the anode target carried thereby. A heat cage is disposed within the housing and surrounds the anode target. The heat cage has a window therein to permit the x-rays to pass therethrough. A vacuum envelope is mounted within a housing and serves to provide a vacuum-tight enclosure for the anode target and the cathode. The vacuum envelope includes a window in registration with the window in the heat cage to permit x-rays to pass therethrough.
