ABSTRACT:
Apparatus is disclosed for providing electrical energy to orbital components of a computed tomography (CT) scanning unit. The apparatus includes a number of high voltage slip rings immersed in an insulating dielectric material. Each slip ring contacts a stationary brush biased to contact the slip ring to insure maintenance of a low resistance path between a stationary source of high potential and a cathode and anode pair of an orbital X-ray tube. A number of low voltage slip rings are further included to facilitate transmission of low voltages to other orbital components of the CT unit. The apparatus is of a compact light-weight design and is mounted to tilt certain components about an axis which intersects a patient's torso to provide CT scanning flexibility.
