Figure 3From: A model-based time-reversal of left ventricular motion improves cardiac motion analysis using tagged MRI data Applying the operation T-1 [ T [ I ( x, y )]] on the deformed grid brings it back to an undeformed state (Fig. a). Similarly, a deformed donut shaped disk is brought back to an undeformed state through application of time reversal (Fig. b).Back to article page
