    摘要： An arrangement includes at least one annular conductor arranged on a rotatable gantry part. The at least one annular conductor is operable to emit electric signals. The conductor is divided into n, where nεN and n>1, rotationally symmetrically arranged annular conductor segments that have no electric connection to one another, and n transmit units. The transmit units are each arranged on different annular conductor segments and each feed different electric signals into the annular conductor segments. Angles between the transmit units and one end of corresponding annular conductor segments are of equal size.
