摘要

Previously proposed techniques based on non-Cartesian or modified Cartesian sampling schemes allow for free-breathing acquisitions with solid motion-robustness. However, residual artifacts such as motion blurring often remain. Techniques including self-gating, motion-weighting, and extra-dimensional reconstruction have been proposed to further improve image quality.
