Calculation of EEG problems with anisotropic conducting media by the finite volume method

A realistic head model with anisotropic conductivity is simulated by the fi nite volume method, which is based on the integral conservation equation. A new mesh discretization method is presented to simulate the realistic head model with anisotropic conductivity. With the method, it Is convenient to calculate anisotropic problems with curved boundary surfaces, and the calcu lation accuracy can be enhanced. The results are compared with analytical s olutions of spherical models. The comparison shows that the finite volume m ethod is of high calculation accuracy.
