Knowledge of both fiber and sheet organization is crucial for understanding of mechanical and electrophysiological processes in heart tissue. Diffusion tensor imaging is able to provide this information in regions where a single dominant fiber or sheet structure is present. For probing more complex fiber architecture, one needs high angular resolution methods such as Q-Ball Imaging (QBI).
