Figure 2From: A model-based time-reversal of left ventricular motion improves cardiac motion analysis using tagged MRI data Vertical motion of large magnitude between two image frames (a) i = 1 and (b) i = 2 with the corresponding vertical phase maps in (c) and (d) gives rise to phase wraps in (d) HARP-based motion map (black arrows point at phase-wrapped regions) computed usingEq. (1). A mask is superimposed on the intensity images to indicate the ROI. The color bar denotes phase change in the interval [-π, π].Back to article page
