Research on VTK and Geomagic-based 3D craniofacial composite modeling / 中国医学装备

ABSTRACT

Objective:To construct 3D craniofacial composite model for clinical diagnosis, simulation and teaching.Methods: Collect head CT image data, and apply MC isosurface rendering method of VTK to reconstruction the 3D models of bones and the dough, then import 3D model into 3D modeling software Geomagic to repair the holes and defects, and finally complete 3D model reconstruction of craniofacial composite model by the comprehensive function of composite.Results: The experiment shows that VTK can reconstruct the 3D craniofacial model quickly, automatically, Geomagic can repair the automatic reconstruction model of defects and holes, the generated composite 3D model can fully and effectively display the three-dimensional composite structures of facial and skull. Conclusion: Using VTK and Geomagic can achieve efficient 3D modeling, and the composite model provided an effective visual reference for the face of the repair, plastic surgery and medical education.
