Claim 15:
16. A method for operating a magnetic resonance tomography system, wherein the magnetic resonance tomography system comprises a magnet unit having a body coil surrounding a patient tunnel, the patient tunnel extending along a longitudinal axis through the magnet unit, and a first transmission interference suppression antenna, wherein the first transmission interference suppression antenna 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; the method comprising:
emitting, by the magnetic resonance tomography system, via the body coil, an excitation signal;
simultaneously emitting a first interference suppression signal via the first transmission interference suppression antenna to reduce an energy and field strength of the excitation signal being emitted out of the patient tunnel; and
providing, by the first transmission interference suppression antenna, a spatial transmission characteristic that is comparable with the body coil of the magnetic resonance tomography system due to the arrangement of the first transmission interference suppression antenna and the body coil.
