In this paper an improved method for three-dimensional (3-D) surface reconstruction from computed tomography slices is presented. Marching cubes (MC) is a popular method for extracting iso-surfaces from discrete (3-D) data. We implemented a simplification of marching cubes, commonly known as marching tetrahedrons (MT).
