Classification: CPC G | IPC G

Claim 0:
1. A magnetic resonance tomography system comprising:
a transmitter operable to generate an excitation signal;
a magnet unit having a body coil operable to emit the excitation signal and a patient tunnel that extends along a longitudinal axis through the magnet unit, the body coil surrounding the patient tunnel; and
a first transmission interference suppression antenna that is arranged inside the magnet unit next to the body coil along the longitudinal axis, such that the first transmission interference suppression antenna is axially arranged between the body coil and an opening in the patient tunnel, wherein the first transmission interference suppression antenna and the body coil are bird cage antennas;
wherein the first transmission interference suppression antenna is configured to provide a spatial transmission characteristic that is comparable with the body coil due to the arrangement of the first transmission interference suppression antenna and the body coil, such that a first interference suppression signal emitted by the first transmission interference antenna reduces an energy and field strength of the excitation signal being emitted out of the patient tunnel.
