Magnetic resonance method and apparatus for suppressing metal artifacts

A magnetic resonance (MR) apparatus for generating magnetic resonance (MR) images of a plurality of slices of an examination person using a Slice Encoding for Metal Artifact Correction (SEMAC) sequence, each slice being associated with a corresponding plurality of sections in a slice-selection direction, the MR apparatus comprising:

• a memory that stores instructions;
• and
• a processor communicatively coupled to the memory and configured to execute the instructions to:
• for each slice, acquire MR data from the corresponding plurality of sections, the MR data being fully sampled in k-space in a reference region located in a center of k-space in a phase-encoding direction and a central section in a slice-selection direction, wherein the MR-data outside the reference region is undersampled in k-space;
• combine the fully sampled MR data from the reference regions of each slice to generate a reference data set;
• and
• reconstruct an MR image of each slice using the MR data of the corresponding slice and the reference data set.
