Single-shot echo-planar imaging (EPI) is commonly
assumed to be immune to subject motion. However, head
movements can reach velocities in the 100mm/s or 100/s
range , resulting in translations and rotations of
several mm or over the course of a typical readout
train (tens of ms). Therefore, a simulation was
performed to determine the effect of such fast movements
on EPI scan quality.
