<p>A high speed communication apparatus for e.g. a Computerized Axial tomography (CAT) scanner (10) utilizes large diameter slip rings (31) to permit continuous rotation of a rotatable gantry (11). A communication signal is applied at a first point (40) on one slip ring, and is terminated by a resistive termination (43) at a point (44) 180 DEG opposite the driving point. The communication signal may then be received at any point on the slip ring. The drive and termination connections to the slip ring may be made by brushes, with the receive connection being made by a physical connection to the slip ring. Alternately, the drive and terminate connection may be made by physical contact, with the receive connection being made by a brush. <IMAGE></p> |
