Figure 15

The constructed 3D volumetric grid mesh from the inner boundary of Fig. 8(a). Fig. 15(a) shows the spherical boundary and (b) shows the generated 3D voxel grid mesh of Fig. 15(a). (c) shows a slice of the total boundaries of the 3D volumetric grid mesh. And (d) shows the color map of the computed thickness values based on the finite difference method.
