Profiles of the LV activity computed through the middle plane of the heart. The OSEM3D, OSEM3D+RR (both with a 5-mm post-smoothing), the two edge-preserving priors (TV with w=0.005, RD with w=4 and γ= 10) and the two anatomy-based priors (both with w=10 and n=9) are compared. These profiles are the mean over 20 noise realizations. In the bottom part, a zoomed-in version of the most interesting areas is shown. a and b demonstrate that a similar behaviour can be expected between MR-based and CT-based anatomical information, where no lesions are considered. In pane c, the MR reconstruction is the one that best follows the contours of the lesion
