Abstract

In a method and apparatus for generating a magnetic resonance (MR) image data set of a target region, MR data for a first number of slices are recorded and the recording of MR data for a second number, which is smaller than or equal to the first number, of different slices takes place simultaneously. A separation algorithm of the parallel imaging is used to determine MR data that are assigned to individual slices from the multi-slice data set produced during the simultaneous recording of the multiple slices. This separation algorithm uses input parameters determined from a calibration data set of the target region, the calibration data set being recorded in a reference scan, after which the MR image data set is reconstructed from the MR data assigned to individual slices, wherein at least part of the calibration data set is also used for reconstructing the MR image data set.
