Coil arrangement for transmitting high-frequency radiation

Abstract

A coil arrangement is for transmitting high frequency radiation. In an embodiment, the coil arrangement includes a transmission coil with a planar design and a passive, tubular part-body coil. The part-body coil is designed to radially enclose an examination volume relative to a direction. The examination volume includes a part of a patient's body. Furthermore, the part-body coil and the transmission coil are galvanically decoupled, and at the same time the part-body coil and the transmission coil are inductively coupled. The transmission coil is designed, by way of an emitted first high frequency radiation, to excite the part-body coil inductively, causing an enforced electromagnetic oscillation. The part-body coil emits second high frequency radiation in the event of an enforced electromagnetic oscillation. The coil arrangement of an embodiment can be used in a magnetic resonance unit without an integrated high frequency unit.
