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.
