1. A method for acquiring measured data that has been recorded simultaneously, via a magnetic resonance apparatus, from at least two slices identified with an examination object comprising at least two different spin types, comprising:
selecting, via the magnetic resonance apparatus, a simultaneous recording of measured data from the at least two slices in which phases that generate field of view shifts are to be imprinted during the recording;
receiving, via the magnetic resonance apparatus, a compensation factor to compensate for interference signals caused by a chemical shift between the at least two different spin types;
computing, via the magnetic resonance apparatus, a compensation phase for the phases to be imprinted in the recording as a function of the compensation factor;
executing, via the magnetic resonance apparatus, the selected simultaneous recording of the measured data;
performing a reconstruction of image data from the measured data; and
displaying, via the magnetic resonance apparatus, the reconstructed image data,
wherein the computed compensation phase is applied to each respective one of the phases to be imprinted during the selected simultaneous recording of the measured data and/or during the reconstruction of image data from the measured data to reduce ghosting artifacts.
