We present a technique for planar imaging (EPI) ghost
reduction at an ultrahigh field human whole body MRI
scanner with a high power gradient insert system. Our
approach can be implemented as post processing without
extra scan. The key of the proposed method is the idea
to derive the parent only region automatically without
defined region of interest (ROI) placed on the parent
image. Phantom experiments were performed using
gradient-echo EPI and spin-echo EPI sequences.
