Computation of multipole moments from incomplete boundary data for Magnetoencphalography inverse problem

Abstract

In this paper, we present a method for reconstructing the dipole sources inside the human brain from radial Magnetoencephalography data measured on the part of the boundary which encloses the source. Combining the proposed method with the direct method provides a good initial solution for an optimization-based algorithm. The method is verified with the numerical simulations, phantom experiments, and a somatosensory evoked field data analysis.
