Abstract: An arrangement to detune a reception antenna in a local coil of a magnetic resonance system, with at least one reception antenna that is fashioned as a loop antenna and that has at least one first capacitance. Radio-frequency signals of a magnetic resonance examination are received via the reception antenna. A switchable detuning circuit contains the first capacitance connected to an oscillating circuit and a first inductance. A reception device to receive a control signal is coupled with the oscillating circuit. The reception device switches the oscillating circuit into a high-resistance state given a received control signal so that a receipt of a radio-frequency signal via the reception antenna is prevented. The reception device is fashioned to receive a wirelessly transmitted radio-frequency control signal. The radio-frequency control signal has a frequency that lies outside of the bandwidth of the radio-frequency signal used for magnetic resonance examination.

Abstract: An arrangement to transmit magnetic resonance signals has a local coil composed of a number of individual antennas for acquisition of radio-frequency signals of a magnetic resonance examination. Preamplifiers amplify the radio-frequency signals, and a transmission device transmits the radio-frequency signals from the local coil to the preamplifiers. The transmission device is fashioned as a readout coil and has a number of individual antennas. The individual antennas of the readout coil are magnetically coupled with the individual antennas of the local coil, with the individual antennas of the local coil and the individual antennas of the readout coil forming a linear MIMO transmission system describable by a transmission matrix.
