Abstract
A multi-dipole graphical model, which is constructed by MCG measurements based on equivalent current dipole (ECD) model or equivalent magnetic dipole (EMD) source model, has been developed. This model can be used in place of the existing heart-torso model for dipole source localization or source estimation. Simulation results are presented, which indicate that the multi-dipole graphical model can effectively approximate the detected MCG.
