摘要： A router (60), for use with magnetic resonance systems (10), selectively routes unique excitation signals, generated by a multi-channel radio-frequency (RF) amplifier, over transmission lines (Tx) to any one of a plurality of connection panels (66) which each accepts at least one RF coil assembly having multiple coil elements (20). Each connection panel (66) includes transceiver ports (68) for connecting at least one conductor (22,24) of the coil elements (20) to a corresponding transceiver channel (T/R). The router (60) selectively routes magnetic resonance signals received by the conductors (22,24) from the transceiver channels (T/R) to a multi-channel RF receiver (41). The coin elements may carry sine-mode currents or uniform currents.
