A method is described to retrospectively correct rigid body motion artifacts in interleaved slice-selective acquisitions. Instead of the conventional slice-by-slice reconstruction, the proposed method relies on reconstructing the 3D volume using all the slices simultaneously using an iterative technique. Simulations demonstrate that, if the motion information is known, it is possible to correct through-plane motion in an interleaved slice-selective acquisition.
