Synthesized averaging using SMASH for elimination of motion artifacts

摘要

In apparatus for magnetic resonance imaging equipped for parallel imaging, in the sense that an array of receive coils can be used to regenerate data at phase-encode gradients interposed between those at which measurements were taken, the full set of data is collected, which is then split into two sets with a greater separation of phase-encode gradients (Figures 13 and 14). These sets are then each regenerated (Figures 15 and 16), enabling spurious data to be excised from the original data set by comparison of the two representations. <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE>
