  • Abstract
    In this study, the forward problem of electrical source imaging (ESI) is solved using the boundary element method (BEM) with realistic head models. The realistic model consists of scalp, skull, CSF, brain and eyes. To get more accurate results quadratic elements are used in the meshes and a new method is proposed for the generation of the quadratic mesh. An accelerated method is proposed for the solution of the potential field.
