To demonstrate the improvement of three‐axial magnetic sensors systems for magnetocardiography when using minimum norm solutions (MNS).
The thesis is proved by using figures of merit and by means of repeated numerical simulations, starting from a BEM model for forward calculations.
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.
The analysis is limited to theoretical sensor systems and can be applied also to realistic measurement set‐ups. Noise is considered uncorrelated. The analysis could be carried out with the help of other figures of merit. More refined models for the human body could be adopted.
The use of three axial sensor systems is encouraged in the field of magnetocardiography.
Numerical analysis of inversion algorithms using three‐dimensional magnetic field data in magnetocardiography have been never carried out.
