摘要

PurposeIn radial imaging, projections may become miscentered due to gradient errors such as delays and eddy currents. These errors may result in image artifacts and can disrupt the reliability of DC-navigation. The proposed parallel-imaging-based technique retrospectively estimates trajectory error from miscentered radial data without extra acquisitions, hardware, or sequence modification.
