1. A computer-implemented method for operating a magnetic resonance device, comprising:
acquiring, using a simultaneous multi-slice technique, a magnetic resonance data set having a total number of slices;
in a sequence section of a magnetic resonance sequence, simultaneously measuring slices associated with magnetic resonance signals using a simultaneity number that is equal to an acceleration factor of at least two;
determining an acquisition order having an association of slices to respective sequence sections of at least one repetition sequence covering all slices of at least one associated concatenation using at least one ordering rule;
evaluating a crosstalk criterion for the determined acquisition order by checking whether a first slice acquired in a last sequence section of at least one of the at least one repetition sequence is directly adjacent to a second slice acquired in a first sequence section of the same repetition sequence; and
if the crosstalk criterion is fulfilled, adapting the acquisition order according to at least one adaptation rule to provide a larger temporal acquisition distance between the acquisition of the first slice and the second slice.
