Field inhomogeneity related phase errors in multi‐shot echo planar imaging (EPI) are directly visualized and analyzed in the spatial frequency domain data or ‘k‐space’. The echo time shift (ETS) technique incrementally moves the position of the echo train and improves the phase error function by redistributing phase discontinuities away from the center of k‐space.
