摘要：
We report on the computation of 3D volumetric optical flow on gated MRI datasets. We extend the 2D "strawman" least squares and regularization approaches of Lucas and Kanade (Lucas and Kanade, 1981) and Horn and Schnuck (Horn and Schnuck, 1981) and show flow fields (as XY and XZ 2D flows) for a beating heart. The flow not only can captures the expansion and contraction of the various parts of the heart motion but also can capture the twisting motion of the heart while it is beating.
