(a) Original frog tongue data with arteries in red and veins in blue. The number of pixels in original 2D data are 634 \(\times \) 515, with pixel dimensions as 0.063 mm \(\times \) 0.064 mm \(\times \) 1 mm. The slice was modified for generating three slices each one-third the thickness as follows. (b) Layer 1: Arterial tree and tissue. (c) Layer 2: Tissue. (d) Layer 3: Venous tree and tissue. Filled triangle—Arterial tree root nodes with Dirichlet boundary condition. Filled inverted triangle—Venous tree root nodes with Dirichlet boundary condition.
