Abstract

We present two algorithms to construct C1-smooth models of skeletal structures from CT/NMR voxel data. The boundary of the reconstructed models consists of a C1- continuous mesh of triangular algebraic surface patches. One algorithm first constructs C1-continuous piecewise conic contours on each of the CT/NMR data slices and then uses piecewise triangular algebraic surface patches to C1 interpolate the contours on adjacent slices. The other algorithm works directly in voxel space and replaces an initial C0 triangular facet approximation of the model with a highly compressed C1- continuous mesh of triangular algebraic surface patches. Both schemes are adaptive, yielding a higher density of patches in regions of higher curvature.
