Abstract
Techniques are provided for operating a magnetic resonance tomography unit. The operation includes determining a B0 field map, determining an excitation of the nuclear spins that is to be achieved, and determining a spectrally selective, generic excitation pulse for transmission by the transmitter via the antenna in dependence upon the B0 field map. The generic excitation pulse is designed to generate the excitation of the nuclear spins that is to be achieved in the patient except for local differences. The operation also comprises determining a spectrally selective, dynamic excitation pulse for transmission by the transmitter via the antenna in dependence upon the B0 field map. The excitation pulse is designed so as to compensate the local differences and thus to generate the excitation of the nuclear spins that is to be achieved in the patient, and outputting the excitation pulse via the antenna.
