Processing steps and results. All tagged images (top) and one DHE image (bottom right) are acquired from the scan. Starting from the tagged image corresponding to the known DHE image (top right), optical flow is used to extract the motion field at all timeframes (step#1; arrows). Then, the measured motion fields are used to estimate the missing DHE images starting from the known DHE image (step#2; arrows). The endo- and epicardium are marked on the DHE images for measuring myocardial thickening. The infarction is identified using full-width at half maximum for measuring transmurality.
