a Representative short-axis slice through the LV myocardial wall. b Simulated simplified 3D microstructure in a 0.9 × 0.9 × 0.1 mm transmural region in the myocardium. Helix angles (HA) ranged from −88° (subepicardium) to 88° (subendocardium). c Magnified 0.1 mm isotropic region showing the simulated cell long-axis, sheetlet and sheetlet-normal directions. d, e Structure tensors reconstructed at 0.1 mm isotropic resolution with kernel sizes of 73 (K7) and 113 voxels (K11). Tensors are displayed as superquadric glyphs and coloured by helix angle. In both cases, v 3,ST is oriented along the voxel-averaged cell long-axis. In contrast, v 1,ST is aligned to the sheetlet-normal direction for K7, and the sheetlet direction for K11. f Illustration of diffusion tensors
