1. A method for generating artifact-compensated combined image data based on first magnetic resonance (MR) data and second MR data, the method comprising:
providing the first MR data and the second MR data, the first MR data having been generated by a first actuation of a magnetic resonance device from an examination area of an examination object using a sequence module, and the second MR data having been generated by a second actuation of the magnetic resonance device from the examination area of the examination object using the sequence module;
registering the first MR data and the second MR data to one another to generate first registered MR data and second registered MR data;
statistically combining the first registered MR data and the second registered MR data on a voxel-by-voxel basis to generate combined image data that comprises a value for each voxel of the examination area to compensate for motion artifacts present in the first MR data and/or the second MR data as a result of changes to the examination area that occur between the first actuation and the second actuation; and
providing the combined image data in electronic form as a data file,
wherein the first MR data comprises first raw data and the second MR data comprises second raw data, and
wherein the registering is performed in the raw data space and is based on a change in phase between the first raw data and the second raw data.
