Abstract
Apparatus comprising a transmission line and a coupler are provided for high data rate communication between rotating and stationary frames of a computerized tomography system. The transmission line comprises individual segments each having a respective first end and a respective second end and having a respective electrical length chosen so that a modulated signal simultaneously applied at each respective first end has a predetermined time-delay upon arrival at each respective second end. The individual segments are arranged so that respective first ends of any two consecutive segments are substantially adjacent to one another and respective second ends of any two consecutive segments are substantially adjacent to one another to avoid time-delay discontinuity in the modulated signal propagating therethrough. The coupler is attached to the stationary frame and is sufficiently near the transmission line for establishing radio coupling therebetween so as to receive the modulated signal being applied to the respective individual segments.
