Abstract :
In human skeletal system, the spine shape is very complex, so its geometric model reconstruction is particularly important. The spine geometric model is created by the main use of reverse modeling method. In this paper, the three-dimensional spine mesh model is reconstructed firstly by marching cubes (MC) algorithmwhich is a popular technique for isosurface extraction from a volume data set. Then, the mesh model is turned into a realistic geometric model by reverse engineering methods. It can be seen that the spine geometric model and its anatomy has a good similarity by comparing and analyzing. This kind of modeling method provides a choice for complex bone structures. And the final geometric model can be imported into three-dimensional modeling software and finite element analysis software for surgical planning and biomechanical analysis.
