Rhinoplasty Surgical simulation Demo
Rhinoplasty Planning and Simulation System based on Volumetric Laplacian Deformation
We present an intuitive rhinoplasty (nose surgery) planning and simulation system to provide high quality prediction of the postoperative appearance. The key component of the system 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 deformation approach suitable for soft tissue simulation. In particular, the system employs a special sketch contour driving deformation interface, which can provides realistic 3D rhinoplasty simulation in real-time, 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.
