Establishment and Simulation of Real Human Head Conductivity Finite Element Model

Object: For realizing the Finite Element (FE) analysis of real human head electromagnetic distribution induced by Trans-cranial Magnetic Stimulation (TMS), a complex human head FE model containing seven organizational structures, i.e. scalp, skull, cerebrospinal fluid (CSF), grey matter, white matter, cerebellum and eyeballs, was established, with the distribution of conductivities, and hence the corresponding tetrahedral FE model. Method: 1) Structural volume models establishment, from which seven organizational structures were distinguished. 2) Conductivity distribution definition, to generate the physical simulation model. and 3) meshed FE model generation. Result: A real human head FE model reflecting features of seven craniocerebral organs and distribution of conductivities. Conclusion: On the basis of five-shell craniocerebral structures, cerebellum and eyeballs are taken into account, providing more materials for the study of magnetic stimulating effects on human neural systems.
