Tracking of in a series of axial slices from base to apex. tracks Supplementary Video 2 ν3 ν3 indicate the sheet-normal direction of the myocardial laminae. In the LV, the radial arrangement of these tracks suggests that the myocardial sheets are aligned near-parallel to the myocardial wall surface in the relaxed heart. A radial arrangement of tracks is also observed in the aorta, whereas ν3 in the RV, they are oriented more longitudinally. In the left and right atria, tracks are generally arranged normal to the local atrial surface.
