High quality isosurface generation from volumetric data and its application to visualization of medical CT data

We propose a method for generating an isosurface from volumetric data sampled with a face-centered cubic lattice. The display quality of the isosurface obtained by our method is greatly enhanced because it generates many good aspect ratio triangle patches. We applied the method to visualization of a colonic wall from medical data. We experimentally compared the resulting surface of our method with those of existing methods, showing the effectiveness of our method.
