Synopsis

Keywords: Artifacts, Data Acquisition, EPI distortionIn this work, we propose a new method for dynamic distortion correction by integrating a tailored EPI trajectory and a joint multi-echo reconstruction, which permits robust dynamic field mapping and distortion correction without compromising spatial resolution. The performance of the proposed method is demonstrated using in vivo experiments.
