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.
