At high fields echo-planar imaging (EPI) becomes increasingly distorted due to imperfections in the magnetic field. This study implemented a technique for using the phase of the EPI to self-correct image distortion and demonstrated its application to phantom and in-vivo human data acquired at 3T and 7T.
