Abstract

Method for acquiring magnetic resonance data of an object with a magnetic resonance imaging apparatus (5), wherein a slice group, whose slices (1) define a contiguous imaging volume (2) and which contains a first number of slices (1), is imaged, wherein in a first number of concatenations the magnetic resonance data for subgroups of the slices (1), each containing a respective second number of slices (1) depending on the first number of concatenations, are acquired, and wherein shimming is performed to increase field homogeneity in the imaging volume (2), wherein, to define the subgroups, the imaging volume (2) is subdivided into at least two disjoint contiguous subvolumes (3), and at least two subgroups are defined for each subvolume (3), each subgroup only containing non-adjacent slices (1) in the subvolume (3), wherein, during acquisition of the magnetic resonance data of each subgroup, shimming is at least restricted to the respective subvolume (3).
