Claim:
1. A radio frequency (RF) volume resonator system for use in an MR imaging system, the RF volume resonator system comprising: a multi-port RF volume resonator comprising a plurality of ports which are positioned at the resonator for exciting and/or receiving RF/MR signals by transmit and/or receive channels, wherein: a plurality of transmit and/or receive channels is provided which each at least comprise an ON/OFF switch for connecting and disconnecting each one transmit and/or receive channel with/from each one of the ports by switching the related ON/OFF switch between an ON and an OFF state, respectively, wherein the ON/OFF switches can be switched between the ON and the OFF state independently from each other by through an individual switch signal, wherein each of the plurality of transmit and/or receive channels comprises a matching network for matching the related port of the RF volume resonator to an impedance of a connected power amplifier or of a connected low noise amplifier, and a control unit for generating the switch signals for selecting at least two of the ports of the RF resonator for connecting with each one of the transmit and/or receive channels for exciting and/or receiving RF/MR signals for conducting an MR imaging of an examination object.
