Medical Imaging Data Implementation into Human FE Head Modelling and Validation

The coupling of new medical imaging data, fractional anisotropy and axonal fiber orientation from Diffusion Tensor Imaging (DTI) of 12 healthy patients called the DTI atlas with the Strasbourg University Finite Element Head Model has been done to improve the brain constitutive material law with more efficient improved heterogeneous anisotropic visco‐hyperelastic material law. The robustness was investigated by validating the brain behavior in terms of local brain motion data from Hardy’s PMHS experiments. A reasonable agreement is observed between experimental and simulation data for the complex three‐dimensional brain motion patterns. This study provides a realistic and feasible method for DTI data incorporation into the brain FE model for the next generation of human head FE modelling.
