Abstract

Magnetoencephalography (MEG) and magnetocardiography (MCG) provide noninvasively information about the normal and pathological electrical activity in the human body. The goal of our research is the determination of the information content of different measurement setups for MEG and MCG. Here, we compare forward and inverse computations of magnetic vector measurements with single-component measurements in MCG. Our results indicate that both the resolution of single- and multiple-dipole solutions improve with magnetic vector measurements.
