Abstract:
This paper is focused on head modeling using the sophisticated realistic finite element method (FEM) with five-layer tissues based on segmented data. First, the location of every pixel of the FEM head model was fixed on according to the registration method based on the magnetic resonance imaging (MRI) and computer tomography (CT) images. Then the location information was rebuilt with the hexahedron pattern in the ANSYS FEM software. Finally, the forward problem numerical computation was performed on this FEM head model. The simulation results verified the rationality and reliability of the model applied on the electroencephalograph (EEG)/magnetoencephalograph (MEG) study. The hexahedron meshing realistic head model combined with the MRI scanner information has potential in the future research of EEG/MEG.
