Fig. 3.
Normalized KB, KN, and KT histograms for GHM fits of the human, dog, and rat heart DT-MRI datasets. The right-most column shows the spatial variation of the normalized KB parameter in a long-axis slice from one dataset of each species, with the color map ranging from -0.7 to 0.7 rad/mm. The plots show KB to be consistent across species as well as homogenous in the heart wall, and KN and KT to be close to zero. Locations where KB has a different sign and value (red arrows) reveal interesting anatomy near the insertions of the right ventricle and at the base close to the valves and the atria.
