Automatic Modeling of Anatomical Structures for Biomechanical Analysis and Visualization in a Virtual Spine Workstation

With the advances in medical imaging, we can now extract quantitative information about human anatomical structures in three dimensions from images of various modalities. But visualization of anatomical structures and finite element analysis are two technical problems for representation of biomedical objects and simulation of physiological behavior. We describe the component of our workstation that contributes to the automatic generation of 3D physical-based meshes used in biomechanical engineering analysis and visualization of complex anatomical structures. This component extends the provision of visual information of the human spine to physical-based analysis for predicting the effects of treatment. These effects range from instrumentation in deformity correction, treatments on the courses of nerves and the resulting strains to the eventual interaction between bone and implants. One of the first applications of our approach was the used of the physical-based model to investigate the injury to human spine among airforce pilots in high G flying.
