ABSTRACT:
A patient receiving region (12) is defined within a stationary CT scanner frame (A). An x-ray tube (B) is mounted on a rotating frame portion (40) for rotation about the patient receiving region on an annular bearing (44, 46, 48). A fluidic slip ring (60) is mounted between the rotating and stationary frames adjacent the bearing for conveying cooling fluid between the x-ray tube and a stationarily mounted, preferably off-site, chiller (D). The fluidic slip ring enables large amounts of heat to be removed from the x-ray tube to maintain the x-ray tube at proper operating temperatures without overheating the interior of the CT scanner, the CT scanner room, or the like.
