Grounded rotating anode x-ray tube housing

In a rotating anode x-ray tube housing of the type having a cathode and rotating anode, wherein the anode has a disk with both a rotational axis and an extended anode plane, the improvement comprising:

• a. a single voltage cable having a terminal end axially mounted within a receptacle, the receptacle is attached to an anode end of the housing and extends inside the housing, whereby the terminal end and the receptacle are contained substantially within the housing;
• b. a longitudinal axis of the single terminal end, and a longitudinal axis of the receptacle, are aligned substantially parallel to the rotational axis;
• and
• c. the terminal end passes through the extended anode plane and is connected to the cathode.

In a rotating anode x-ray tube housing of the type having a cathode and rotating anode, wherein the anode has a disk with both a rotational axis and an extended anode plane, the improvement comprising:

• a. a cathode cable having an attached Federal Standard plug mounted within a Federal Standard receptacle, wherein the receptacle is attached to an anode end of the housing and extends into the housing;
• b. the plug and receptacle are contained substantially entirely within the housing;
• and
• c. the plug has a longitudinal axis parallel to the rotational axis.

In an diagnostic x-ray tube housing of the type having a cathode and rotating anode, powered from 50 kV to 150 kV with one high-voltage cable connected to the cathode, wherein the anode has a disk with both a rotational axis and an extended anode plane, the improvement comprising:

• a. the cable has a single end portion recessed in a well which extends into the housing;
• b. the end portion and well are contained substantially entirely within the housing;
• c. a longitudinal axis of the cable end is aligned with a longitudinal axis of the well;
• d. both the longitudinal axis of the cable and the longitudinal axis of the well are parallel to the rotational axis;
• and
• e. the cable end passes through the extended anode plane before being connected to the cathode.
