Research on reconstruction of equal diameter pipe surface based on Voronoi diagram

Aiming at the low efficiency and low accuracy of existed algorithms of reconstructing equal diameter pipe surface, Voronoi diagram and its improvement were discussed in this paper. The relationship between the inscribed circle with maximum radius of slice contour and Voronoi diagram was given. A novel algorithm of solving the center curve and radius of equal diameter pipe surface based on Voronoi diagram was then put forth. The reconstruction result of blood vessel validates its efficiency.
