Claim 11:
12. 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;
arranging a calibration antenna at a location at a greater spacing from the transmitting antenna than the plurality of sensors; and
detecting, by the calibration antenna, a field strength produced by the first test pulse,
wherein the determining the interference suppression signal takes place as a function of the far field transfer function, and
wherein determining the interference suppression signal as a function of the far field transfer function comprises determining the interference suppression signal also as a function of the detected field strength of the calibration antenna.
