摘要：
A magnetic resonance tomography unit and a method for operating the magnetic resonance tomography unit are provided. The magnetic resonance tomography unit has a transmission interference suppression device with a transmission interference suppression control system, a sensor, and a transmission interference suppression antenna. The transmission interference suppression device is configured to acquire, with the sensor, an excitation signal of the transmitter, and determine, with the transmission interference suppression control system, a transmission interference suppression signal dependent upon the acquired excitation signal of the transmitter. The transmission interference suppression device is configured to transmit, via the transmission interference suppression antenna, the transmission interference suppression signal, 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.
