Abstract :
A realistically shaped finite element (FE) model of the human head was developed based on magnetic resonance images (MRI). Using this model, the potential and current density distributions in the head were simulated by solving the forward problem of Poisson´s equation when the injection current was applied on the surface of the scalp. Based on the simulation result and the FE model analysis, a modeling improvement is proposed in order to achieve the best simulation result for the particular requirements of the resistivity reconstruction of the human head
