A
Nyquist ghost correction of EPI is propose, which determines the phase
correction differences between channels and slices with high accuracy in a
preparation step from a set of navigator echoes. Taking this calibration into
account, only one single correction needs to be determined dynamically for
all slices and channels during the EPI series, greatly improving stability.
