Abstract :
Instead of the human torso model in study of inverse solutions of sources estimation, a graphical model is developed, which is constructed by the equivalent current dipole (ECD) or equivalent magnetic dipole (EMD) source model and MCG measurements based on the sub-sectional approximate principle of the magnetic field zero value curve. The simulations results available indicate that a current multi-dipole graphical model effectively describe the magnetic field between detected MCG and cardiac current sources.
