Abstract

Using cylindrical parameterization, the 3D mesh surface extracted from colon CT scan images is parameterized onto a cylinder, and afterwards visualized with a modified Chamfer distance transformation of the original CT images with regards to the colon centerline/boundary distance. The cylinder with information from distance transformation is then unfolded with numerical integration along its circumferential direction and mapped to a plane, which approximates the view of a colon cut open along its length.
