The disclosure relates to a method for calibration in a magnetic resonance (MR) imaging procedure, in which MR imaging data is acquired simultaneously from a multiplicity of slices of a subject under examination, wherein at least one subsampled calibration dataset is generated from a fully sampled reference dataset of an individual slice by rearranging an order of the data points in the reference dataset. In addition, a reconstruction dataset, which is used to assign MR imaging data to the individual slice, is calculated based on the rearranged order of the at least one calibration dataset, wherein the MR imaging data of the individual slice is subsampled in k-space.
