In this work, we report a self-calibrated non-Cartesian sensitivity encoding scheme integrated with image-based motion correction for whole-heart coronary MRA. Results show that the proposed method can greatly reduce the artifact level in images with different undersampling factor, thus allows further reduction in scan time without significant sacrifice in image quality.
