| Abstract: | Objective To study the modeling and simulation of surgical operations in soft tissue based on real patient's CT data and implement the simulation of cleft lip operation partly. Methods Thin-layer CT scanning was employed to obtain the original data. Image segmentation was made based on mean clustering. A visualization model was reconstructed and optimized using marching cubes of VTK(Visualization Toolkit) technology. The 3D Widgets' framework of VTK was used to build behaviors of virtual scalpels.
