Correction of motion effects in magnetic resonance (MR) data acquired using a magnetic resonance system

A computerized method for correcting motion effects in magnetic resonance (MR) data acquired using a magnetic resonance system, the method comprising:

• a) loading into a controller at least n, where n>1, sets of multislice MR data, each of which has been acquired simultaneously from n identical slices of an examination subject, wherein the n slices are encoded with different phase patterns for each set of multislice MR data;
• b) the controller performing a first separation operation which separates the loaded sets of multislice MR data into n first single-slice MR data of the n slices;
• c) the controller determining slice-specific calibration data for a parallel imaging method for separating simultaneously acquired slices based on the first single-slice MR data;
• d) the controller performing a second separation operation which, using the determined slice-specific calibration data and an associated parallel imaging method for separating simultaneously acquired slices, separates each of the loaded sets of multislice MR data into n second single-slice MR data of the n slices;
• e) the controller determining motion correction parameters based on the second single-slice MR data, which parameters compensate for motion effects between the loaded sets of multislice MR data;
• and
• f) the controller determining one motion-corrected set of multislice MR data each per loaded set of multislice MR data from the loaded sets of multislice MR data using the determined motion correction parameters.
