It
is long known that the myocardial architecture has its functional
significance. However, up to now there are no models that can fully explain
the relationship between myocardial fiber structure and the mechanism of
cardiac motion. In this study, we proposed using diffusion tensor imaging and
fiber tracking technique to perform virtual dissection of the myocardial
fiber architecture. We found that the
