A computed tomography (CT) scanner apparatus includes an improved arrangement for transferring high voltage electrical energy between a stationary gantry (40) and a rotating assembly (42) which carries the X-ray source (44) and has an opening defining an aperture to receive a part of a patient. A first axis (36), about which the assembly rotates, passes through the aperture. The apparatus includes a number of slip rings (56, 58) which are used for effecting the transfer of the electrical energy. Respective portions of the gantry and rotating assembly define a cavity which contains an insulating di-electric fluid in which the slip rings are immersed. The apparatus is of compact design and, further, the rotating assembly and the slip rings can be tilted about a second axis which intersects the first axis. <IMAGE> |
