Abstract
An inductive rotary joint for computer tomographs includes an inverter and an inductive rotary coupler. A primary winding of the inductive rotary coupler is fed by the inverter via a line, with energy transmitted by the inductive rotary coupler being supplied to a load through a secondary winding. The line includes at least two coaxial lines, each coaxial line having an outer conductor or shield with the two outer conductors or shields being interconnected along a major part of their length, and an inner conductor, with the inner conductors being supplied by the inverter with voltages, the sum of which is substantially equal to zero.
