Analysis of errors in neuromagnetic localization of multiple current dipole sources

Abstract

Describes a calculation algorithm for the neuromagnetic localization of multiple current-dipole sources and a computer simulation study using the method. In the simulation, source localizations were obtained for dipolar and multipolar field patterns subject to different levels of Gaussian noises. The results show that the present algorithm is useful for localizing multiple dipoles in low signal-to-noise ratio conditions and that the location accuracy depends on the signal-to-noise ratio, the distance between dipoles and the depth of the dipoles.
