Claim 13:
14. A method for operation of a magnetic resonance tomography unit, the method comprising:
emitting a predetermined first test pulse with a transmitter via a transmitting antenna;
detecting, by a plurality of sensors, a field strength produced by the first test pulse;
determining, by a transmission interference suppression facility, a far field transfer function for the transmitting antenna as a function of the first test pulse;
receiving information about an excitation signal with a plurality of sensors;
determining, by a transmission interference suppression controller, an interference suppression signal as a function of the information such that on emitting the interference suppression signal via the transmission interference suppression antenna, a field strength of the excitation signal is reduced at a predetermined location in a far field;
emitting the interference suppression signal via the transmission interference suppression antenna;
emitting a predetermined second test pulse with the transmission interference suppression facility via the transmission interference suppression antenna;
detecting, by the plurality of sensors, a field strength produced by the second test pulse; and
determining, by the transmission interference suppression facility, a far field transfer function for the transmission interference suppression antenna as a function of the second test pulse by way of the transmission interference suppression facility,
wherein the determining of the interference suppression signal takes place as a function of the far field transfer function for the transmitting antenna and as a function of the far field transfer function for the transmission interference suppression antenna.
