This article presents a technique, based on PC system, of skull surface triangulation representation for coronal CT images. First, the end-user selects interactively a point within the Region of Interest (ROI), and the computer will automatically position the selected ROI. The boundary points of the ROI is extracted and ordered according to their spatial orientation. Then, the boundary points between two adjacent slices are triangulated by virtual of the optical local morphology. We briefly introduce the technique how to get the patch of skull defect in the commercial software package Surfacer. So the geometric representation using triangular patch can be produced by rapid prototyping and tooling. Finally, the experimental results show that the technique proposed is efficient for the reconstruction of broken part of skull surface and convenient to surgical repair of skull defect. Also, we have found that the technique is robust in implementation.
