1. A computer-implemented method for recording, using a magnetic resonance device, a magnetic resonance image data set of a region of a patient, the method comprising:
operating a magnetic resonance data acquisition scanner to execute a multislice imaging algorithm using simultaneous at least partial undersampling in a slice plane to read out magnetic resonance data simultaneously from a plurality of excited slices, the magnetic resonance data being separated into at least two portions, each respective one of the at least two portions being associated with a respective subregion of sampled k-space in the slice plane of the magnetic resonance data having a different fixed degree of sampling;
calibrating, via the magnetic resonance data acquisition scanner, a slice separation algorithm using reference data that is recorded in a separate reference scan;
separately executing, via the magnetic resonance data acquisition scanner, for each respective one of the at least two portions of the magnetic resonance data associated with a respective subregion of the sampled k-space, the calibrated slice separation algorithm to the simultaneously read out plurality of excited slices to generate respective slice-separated portions, the calibrated slice separation algorithm utilizing a different respective slice separation kernel for each respective one of the at least two portions of the magnetic resonance data;
executing, via the magnetic resonance data acquisition scanner, an undersampling algorithm to undersampled magnetic resonance data associated with the slice-separated portions having a fixed degree of sampling associated with undersampling to compensate for the at least partial undersampling in the slice plane; and
recombining slice-by-slice, via the magnetic resonance data acquisition scanner after compensation of the undersampling in the slice plane, the respective slice-separated portions of the magnetic resonance data to generate the magnetic resonance image data set.
