The actual gradients present in the measurement volume are measured by a field mapping device in the measurement volume of the MR system. The trajectories along which k-space is scanned during the acquisition of the measurement data are calculated on the basis of the measured actual gradients. An artifact-free image data set is reconstructed from the acquired measurement data under consideration of the calculated trajectories, and is displayed and/or stored.
