Abstract: A new technique to measure local planar strain in left ventricular myocardium using two-dimensional tagged MR images is presented. This new technique is computationally fast, is fully automated, and generates dense motion estimates. It is based on using a 1-1 SPAMM tag pattern which comprise several one-dimensional sinusoidal tag patterns at different frequencies. A local deformation of the myocardium produces a variation in the local frequencies of these patterns, which can be used to compute... (Update)
