1. A radio frequency (RF) receiver system for use in a magnetic resonance (MR) imaging system, the RF receiver system comprising:
two or more RF receive coil elements, and two or more RF signal channels, each RF reciever coil being coupled to a respective RF signal channel
each RF receive coil element comprising a signal generator for providing a compensation signal and an excitation path (4), wherein the excitation path is configured to couple the compensation signal into the RF receive coil element, wherein the each RF receive coil element is configured for reducing residual coupling in the RF receiver system by means of the compensation signal coupled into the RF receive coil element, wherein
the two or more RF receiver channels are in mutual correspondence by a communication circuit coupled in a transverse direction and
for each RF receiver coil element its compensation signal is dependent on the outputs of one or more respective other RF receiver coil element of the RF receiver system and for each RF receiver coil element the transverse communication circuit is configured to provide the compensation signal to the respective excitation path.
