3D image based navigators (iNAVs) provide an opportunity to measure whole volume non-rigid beat-to-beat motion of the heart. In this work, we show that we can use optical flow to estimate motion from 3D iNAVs. The Alternating Direction Method of Multipliers is used to minimize the optical flow cost function, where total variation regularization has been imposed.
