An Improved Facial Orthopedic Surgery Planning System with Pre-processing FEM Modeling
نویسندگان
چکیده
Finite Element Method(FEM), which is based upon continuum mechanics and the physics of materials, is one of the most widely used deformation method in digital biomedical area. Unlike other light-weighted deformation models (Mass-Spring, Free Form, Chainmail, BEM, etc)using in other areas, FEM gets the most accurate deforming results in the cost of large scale of computation. In this paper, we present an improved Facial Orthopedic Surgery Planning system using pre-processing FEM modeling. This planning system calculates and simulates the bone-reshaped surgical result of facial soft issue deformation more quickly. According to the specific demands of the facial surgery planning system, we designed and implemented FEM modeling in our own way and improved the computational efficiency. Finally we validate and represent the deformation results, compare our method and results with the traditional one.

Facial Modeling for Plastic Surgery Using Magnetic Resonance Imagery and 3D Surface Data
We describe a novel facial modeling and real-time pre-surgery planning + visualization tool for surgical and esthetic plastic surgery. The modeling pipeline accepts geometry both in the form of Magnetic Resonance Imagery (MRI) and/or 3D facial surface scans. The MRI data is first used to segment the skin surface as well as the underlying tissues of interest. Textures taken with a digital camera...
