Abstract:
Objective To generate finite element models of human head based on segmented computer tomography data.Methods A four-step procedure was adopted to configure the coarse mesh.The method of longest edge propagation path and the edge collapse were used to refine and optimize the final mesh.The method was evaluated by means of computer simulations in a 3-concentric-sphere head model and a three-layer realistic geometry human head model.Results The present simulation results showed reliability and rationality of the finite element computation,thus indicate the suitability of the developed method.Conclusion A multi-tissue finite element model is obtained by using this method.It can be applied to the computation of finite element based bio-mechanics and bio-electromagnetism.
