Figure 3.
Global superposition of six cerebral arterial trees in virtual reality space. The first column shows the original gray-scale MRA images. The second column is the reconstructed vascular skeleton (red) of the arterial tree which includes diameter, centerline, and network connectivity information. Three-dimensional parametric structured meshes (blue) are shown in the third column. The last column is the global superposition with MRA (white), vascular skeleton (red) and parametric mesh (blue).
