1. A magnetic resonance tomography unit comprising:
a magnet unit;
a transmitter;
a transmitter antenna operable to excite nuclear spins;
a transmission interference suppression device comprising:
a transmission interference suppression control system;
a sensor; and
a transmission interference suppression antenna,
wherein the transmission interference suppression device is configured to:
acquire, with the sensor, an excitation signal of the transmitter for exciting nuclear spins;
determine, with the transmission interference suppression control system, a transmission interference suppression signal dependent upon the acquired excitation signal of the transmitter; and
transmit the transmission interference suppression signal via the transmission interference suppression antenna, so that at a predetermined location outside the magnetic resonance tomography unit, the excitation signal emitted by the transmitter via the transmitter antenna is attenuated,
wherein the sensor is arranged in a far field of the transmitter antenna, and the predetermined location of the attenuation is a location of the sensor, and
wherein the predetermined location is specified by a distance defined by regulation for an EMC limit value.
