The invention relates to an MR coil module for use in an MR imaging system for receiving and/or transmitting RF signals. In order to provide an MR coil module which allows a modular and user definable configuration of an RF coil system and which provides a high SENSE factor (>2), the MR coil module according to the invention comprises: at least two coil elements (21-26) positioned next to each other, a preamplifier (51-56) for each coil element (21-26), a signal bus (40) for transferring RF signals between said coil elements (21-26), an output means (10) and an input means (9), an output means (10) for outputting RF signals from the MR coil module (1), an input means (9) for inputting RF signals into the MR coil module (1), switching means (6) for switching the connections between said coil elements (21-26), said input means (9) and said output means (10), wherein said output means (10) and said input means (9) are adapted complementary so as to enable electrical and mechanical connection of the module (1) to other modules.
