HIGH QUALITY ACCURATE SURFACE TRIANGULATION FROM A SIMPLEX MESH

摘要

A method is disclosed for improving the accuracy of a surface mesh describing a segmented 3D object in a 3D image. A dual triangulation surface mesh is provided for a simplex surface mesh of the 3D object. Errors are reduced in the representation of the 3D object caused by the dual triangulation surface mesh by shifting triangulation nodes of the dual triangulation surface mesh of the segmented 3D object for providing a more accurate triangulation surface mesh. The 3D image is preferably a medical 3D image. Furthermore, a medical workstation, comprised in medical imaging system is disclosed for implementing the above improvement.
