Highly Efficient Respiratory Gating in Whole Heart MR Employing Non-Rigid Retrospective Motion Correction

Respiratory motion artifacts in coronary MR scans were retrospectively corrected using a non-rigid motion model acquired interleaved during the sequence pauses in each heart cycle. Gating efficiency could be doubled without loss in image quality.
