Abstract:
In a magnetic resonance tomography apparatus having a gradient coil which produces a gradient field according to a temporally variable reference quantity and having a radio-frequency system which emits a radio-frequency signal during a transmission time segment and which receives a radio-frequency signal in a reception time segment, said magnetic resonance apparatus having at least one component in which eddy currents are produced by said gradient field, a method for prescribing a said temporally variable reference quantity comprising:generating said temporally variable reference quantity with no pre-distortion of said reference quantity for compensating said eddy currents in a first time segment that is not a transmission time segment or a reception time segment for said radio-frequency signal, and with a pre-distortion of said reference quantity for compensating said eddy currents in a second time segment that is a transmission time segment or a reception time segment for said radio-frequency signal.
