Biomimetic modeling approach for cranial microstructure based on micro-CT technology

For the limits of the symmetrical structure and uncontrollability in current cranial microstructure modeling, a biomimetic modeling approach based on micro-CT technology is proposed in this paper. At the beginning, the natural cranial sample is scanned by micro-CT technology and reconstructed using reverse engineering. Then through the study of the reconstructed sample, it is found that the cranial microstructure is configured by three parts of special architecture nets, cavity and connecting pipe. So after the parametric analysis, modeling to the three parts respectively, and assembly them in a certain form, the partial biomimetic model of the cranial microstructure was established. The results indicate that the biomimetic model and the natural cranial microstructure show high similarity.
