Abstract :
We report on the computation of 3D volumetric optical flow on gated MRI datasets. We extend the 2D least squares and regularization approaches of Lucas and Kanade [4] and Horn and Schunck [3] and show flow fields (as XY and XZ 2D flows) for a beating heart. The flow not only can capture the expansion and contraction of various parts of the heart motion but also can capture the twisting motion of the heart.
