Paper Abstract

A method for neuromagnetic imaging of impressed current density in complex volume conductors using current source density calculations is investigated. The method is applied to phantom experiments with one and two curmnt dipoles in two different volume conductor phantoms. The results indicate that strong filtering effects, inherent in the Maxwell equations, pretend volume current effects in the images. The method yields better localization and spatial resolution of single and multiple sources compared with conventional total current density imaging.
