1. A cooling device (70, 70′, 70″) for an associated x-ray tube (26) comprising:
a fluid inlet (72, 72′, 72″) which receives a supply of cooling fluid from an associated source (52);
a hollow cover member (110, 110′, 110″) in fluid communication with the inlet, the cover member:
including a wall (118, 118′, 118″) which defines an aperture (126, 126′, 126″) sized for receiving a portion (34) of the associated x-ray tube therethrough,
defining, at least in part, an interior annular flow path (152, 152′, 152″) for cooling fluid to circulate around the portion (34) of the associated x-ray tube, and
providing at least one fluid outlet (140, 140″, 156, 156′) through which cooling fluid exits the cover member at a plurality of locations around the portion of the associated x-ray tube.
