Abstract
A computerized tomography system includes a stationary section (A) and a rotating section electrically linked by at least one interconnecting slip ring (D). On one side the slip ring (D) is configured as a series of electrically conductive segments (20A-20H) separated by non-conductive interruptions (22A-22H). On the other side a like number of transmitters (26A-26H) is in selective electrical contact with the conductive segments (20) depending on a position of the rotating frame. Also included is a de-multiplexer (40) which takes image data from the plurality of receivers (RxA-RxH) and rearranges the image data in a determined sequence. Also shown is an angular encoder (46) for providing angular displacement signals (44) to the de-multiplexer (40) for assistance in reconstructing the data channels (30) in the determined sequence.
