Nose Surgery Simulation Based on Volumetric Laplacian Deformation

This paper presents an intuitive nose surgery simulation system, to provide high quality prediction of postoperative appearance. The key component is a novel volumetric Laplacian deformation tool inspired by the state-of-the-art differential surface deformation techniques. Working on the volumetric domain and incorporating inhomogeneous material from CT data make the new approach suitable for soft tissue simulation. In particular, the system employs a special sketch contour driving deformation interface, which can provide realistic 3D nose surgery simulation with intuitive and straightforward 2D manipulation. Clinical validation using post-operative CT data demonstrated that the system can provide prediction results of high quality. And the surgeons who used the system confirmed that this planning system is attractive and has potential for daily clinical practice.
