Tomographic vascular tractograms. (a-l) Representations and visualizations of the microvasculature for a lectin-TRITC stained apical short-axis slice (as shown in Fig. 1e). (a) Tomographic vector field representation of the vascular directional primary eigenvector in a lectin-TRITC stained apical short-axis slice (as shown in Fig. 1e and plane 1 of Fig. S13). Tomographic vascular tractogram determined along the primary eigenvector (b) and magnified view of the posterior left/right ventricle border area (c). Scale bar, 100 μm. (d) 3D ellipsoid glyph representation of the tensor field for the representative slice in (a). (e,f) Tomographic vascular tractograms determined along the secondary (e) and tertiary (f) eigenvectors. (g) Skeleton axial view representation of the vascular network. (h–l) 3D magnified views of the area α To (g). Glyph tensor field representation (h) and vascular skeleton (i) with corresponding vector field representations (j,k). In (j) colors encode directional information, while in (k) a cold-hot pseudo-color map encodes the principal eigenvector projection’s magnitude along the vertical axis. (l) 3D rendering of the fiber tracts corresponding to the magnified area. (m) Tomographic directional vascular tractogram in a lectin-TRITC stained basal short-axis slice (plane 3 of Fig. S13). (n,o) Magnified skeleton representation of the microvasculature in λ and corresponding tractogram. (p,q) Skeleton representation of the microvasculature and corresponding tractogram for a representative lectin-TRITC stained sagittal slice (as shown in Fig. S1h). Scale bar, 500 μm.
