    Abstract

    Cardiac fiber orientation is one of the main determinants of fiber stress and strain during ejection. We measured fiber orientation using magnetic resonance diffusion tensor imaging (MR-DTI). Traditional methods to quantify the cardiac fiber field rely on the definition of the coordinate system. We propose to use the entity 'divergence' for characterization of the continuity of the myocardial fiber structure. The divergence is a scalar quantity with a value that is independent of the actual choice of the coordinate system. Moreover, the divergence value of the fiber field expresses the degree of uniformity of stress along the fiber direction. The divergence of the myofiber field appeared to be
