Abstract

We consider the problem of localization of magnetic field sources in magnetocardiography using the 1D multidipole model. In real conditions, the experimenter has to deal with an underdetermined, ill-conditioned system. Regularizing procedures were used to obtain a stable solution. The work investigates the resolution of the method, the reconstruction quality (determining the spatial parameters of a multidipole: the depth and amplitude of the dipole moment) and the stability of the solution. The computer simulation used the singular value matrix decomposition method and Tikhonov regularization.
