Figure 2

volume distortions and spin history effects, sagittal reformations of axially acquired data. Top row, left: volume free of distortions and spin-history effects; top-right: volume acquired in presence of left-right rotation and without prospective motion correction. Interleaved slice ordering is obvious due to the misalignment between the odd and even interleaves. Bottom row, left: volume acquired with sequential slice ordering in a presence of a single abrupt nodding motion; bottom-right: similar motion but interleaved acquisition. Top row is from (Speck et al., 2006); Bottom row from http://imaging.mrc-cbu.cam.ac.uk/imaging/CommonArtefacts.
