Synopsis
In this study, we developed a groupwise registration and tractography framework to investigate the global myofiber arrangement of large mammalian sheep hearts. To demonstrate the potential application of the proposed method, a novel description of sub-regions in the intraventricular septum (IVS) is presented. The study focuses on one fiber-bundle in the posterior junction and three fiber-bundles in the anterior junction.
