Purpose – To demonstrate the improvement of three-axial magnetic sensors systems for magnetocardiography when using minimum norm solutions (MNS). Design/methodology/approach – The thesis is proved by using figures of merit and by means of repeated numerical simulations, starting from a BEM model for forward calculations. Findings – We found out that both for under-determined and over-determined problems two figures of merit show better performance of a three-axial sensor system when compared with two mono-axial sensor systems. We also showed the positive impact of three component magnetic field data on MNS by means of repeated simulations.
