Development of Realistic Head Models for Electromagnetic Source Imaging of the Human Brain

Abstract

In this work, a methodology is developed to solve the forward problem of electromagnetic source imaging using realistic head models, For this purpose, first segmentation of the 3 dimensional MR head images is performed Then triangular, quadratic meshes are formed for the interfaces of the tissues, Thus, realistic meshes, representing scalp, skull, CSF, brain and eye tissues, are formed, At least 2000 nodes for the scalp and 5000 for the cortex are needed to obtain reasonable geometrical approximation Solution of the forward problem using our previous Bound and Element Method (BEM) formulation with quadratic elements remains to be made,
