Patent ID: 8659295

Claim:
A method for acquiring a magnetic resonance image of a subject, comprising the steps of: operating a magnetic resonance data acquisition unit with a sequence to acquire magnetic resonance data from an examination subject in the magnetic resonance data acquisition unit, by exposing the subject in said sequence to multiple alternating fields that prepare respective magnetizations, with respectively different frequencies, of nuclear spins in the examination subject, and implementing a readout sequence for signal values from the examination subject comprising magnetic resonance data representing a plurality of pixels of the examination subject; in a processor, evaluating said magnetic resonance data pixel-by-pixel dependent on the signal values determined after the preparation of the magnetizations for the different frequencies of the alternating fields; in said processor, determining magnetic field data representing spatially resolved information with respect to a basic magnetic field generated in said magnetic resonance data acquisition unit, said spatially resolved information being correlated with said plurality of pixels; and implementing at least one of the acquisition of said magnetic resonance data and the evaluation of the acquired magnetic resonance data depending on said magnetic field data.
