Abstract
A high speed communication apparatus for a Computerized Axial Tomography (CAT) scanner utilizes large diameter slip rings to permit continuous rotation of a rotatable gantry. A communication signal is applied at a first point on one slip ring, and is terminated by a resistive termination point 180.degree. opposite the driving point. The communication signal may then be received at any point on the slip ring by a receive connection and a matching receive connection which are 180.degree. opposite one another. The drive and termination connections to the slip ring may be made by brushes, with the receive and matching receive connections being made by a physical connection to the slip ring. Alternately, the drive and terminate connections may be made by physical contact, with the receive and matching receive connections being made by brushes.
