摘要

An optical communication link coupling a rotating part of a gantry of a computerized tomographic scanner to the stationary part of the gantry. The link comprises an arcuate hollow light conductor having one part rotating with the rotor of the gantry and the other part fixed to the stator of the gantry. Signal bearing light beams are transmitted into the link and are subsequently received from the link after transversing at least a portion theroef.
