Abstract
Echo planar imaging (EPI) is one of the fastest techniques for acquiring MRI data. This method incorporates rapid changes in readout gradient polarity and amplitude to refocus the signal of a single spin excitation, producing the required echoes for an entire image. The acquisition time for one slice is one TR period, which lasts as little as 40 ms, and the process is repeated for the number of slices desired.
