Embodiment Construction

[0044] Attached figure 1 A magnetic resonance (MR)-system 1 is shown and includes a magnetic resonance device 2 having a feed coil in the form of a birdcage body coil 3 fixed to the device as a whole body coil, the whole body coil having a longitudinal axis L. The longitudinal axis L corresponds to the fixed z-axis. The magnetic resonance system 1 further has a first magnetic resonance local coil system 4 arranged in the field of view of the body coil 3. The local coil system 4 has a plurality of local magnetic resonance transmission coils, at least two of which are different in shape. Here, only one local magnetic resonance transmission coil 5 (local coil) among the plurality of local magnetic resonance transmission coils is displayed.

[0045] The shown local magnetic resonance transmission coil 5 is in the shape of a flat, circular coil ("loop"), which is electrically inductively (and wirelessly) coupled with the B1 excitation field generated by the birdcage coil 3. This cou...

Abstract

The invention provides an MR local coil system, mr system and method of operation. The MR local coil system has a plurality of local MR-transmitting coils which can be coupled inductively to at least one feeder coil of an MR apparatus, wherein by means of local MR-transmitting coils local B1-exciting field which is differently structured to each other can be generated. The MR system has an MR device with a supply reel and a local MR local coil system, wherein the local MR-transmitting coils and the supply reel are inductively coupled, the MR-device is used for selectively producing a differently structured global B1 field component of a global B1-exciting field produced by the supply reels, and the differently structured global B1 field component and MR-transmitting coils of the local MR local coils system are coupled. One method is used to operate the MR system in which differently structured B1 field of the global B1-exciting field component is generated by the supply reel of the MR system.
