PROBLEM TO BE SOLVED: To provide an apparatus that communicates between a stationary frame and an anular revolving frame of a computerized tomograph. SOLUTION: Transmission line 40 attached to the revolving frame, positioned around it, consisting of individual segments 50 and 60, and being driven differentially is provided. A transmission line shield afixed to the transmission line 40 shielding the transmission line 40 from an electromagnetic radiation and definning a passage along the revolving frame, is provided. A Differential coupler 100 set on the stationary frame, positioned within a passage sufficiently near the transmission line 40 for establishing radio coupling with the transmission line to receive the modulated signal given to an individual segments is provided. Individual segments 50 and 60 have electric heads separately which are selected in order to have delay when a modulation signal given to each end of the first segment 52 and 62 simultaneously reaches each end of the second segment 54 and 64. |
