Abstract
Measures of a velocity component during a plurality of time frames of cyclical motion of a region of interest are obtained using contrast cine MRI techniques. Trajectories of the region of interest are calculated in a backward direction and in a forward direction. The trajectories are then combined to define a motion trajectory. The forward and backward trajectories are weighted prior to combining with the forward trajectory being more heavily weighted for early frames and the backward trajectory being more heavily weighted for late frames.
