Abstract

Cortical imaging technique (CIT) is an effective spatial enhancement approach to noninvasively image dynamic brain activity with high spatial resolution. The accuracy of forward problem in CIT has an importance on the accuracy of estimated cortical potentials. In this paper, we investigate finite-element-algorithms relating the cortical potentials to the scalp potentials. The numerical accuracy of the FEM algorithm being considered was assessed by computer simulations. The present simulation results suggest that the present FEM model has the similar accuracy as compared with the conventional model, but offers convenience in the application. The present algorithm has been tested in a realistic geometry head model.
