Assignee: SIEMENS HEALTHINEERS AG
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 15:
16. 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,
wherein the transmission interference suppression control system has a signal connection to the transmitter that is configured to receive an information item regarding the excitation signal, and
wherein the transmission interference suppression control system is configured to determine the transmission interference suppression signal dependent upon the received information item.
