  ABSTRACT: In recent year, a multipole graphical model, which is constructed by using individual MCG measurements based on the equivalent current dipole (ECD) or equivalent magnetic dipole (EMD) source model, has been developed with the aim of instead of the volume conductor model in the inverse solution of cardiac source estimation. In this paper, two graphical models known as the double magnetic dipole source model (DMD) and the dual current dipole source model (DCD) are introduced. The simulation results and the comparison of two evaluation criteria, i.e. average GOF (Goodness of Fit) and average RMSE (Root Mean Square Error), indicated that both multipole graphical models can provide a good representation of dynamic magnetic field from the noninvasively detected MCG- recordings, even when the heart is of the dilation. The time-averaged sources localization error and the RMSE for both models are demonstrated, and the characteristic of two multipole models is discussed.
