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.
