Figure 2

An infracted sheep heart viewed from (A) its anteriorinfarcted wall and (B) the remote zone in its lateral wall. Fibers were colored according to median helix angle values computed along individual trajectories. (C) Plot of maximum, median and minimum helix angles in the remote zone of the infarct as they vary from endocarduim to epicardium. A shift to more positive helix angle values in the remote zone as a result of the remodeling process can be observed (B,C). The normalized quadratic error (NQE) of these fibers is 1.77, consistent with a high quality dataset.
