MINIMUM-NORM ESTIMATION IN A BOUNDARY-ELEMENT TORSO MODEL

The paper deals with the bioelectric and biomagnetic inverse problems. The authors present a estimate primary-current distributions in a hom ogeneous, realistically shaped boundary-element torso model. The recon struction surface is triangulated to keep the procedure computationall y feasible. The minimum-norm estimate is computed on the basis of sepa rate electric and magnetic signals, as well as from combined data. The method can be used both for heart and brain studies. Simulation resul ts for current-dipole sources in a homogeneous realistic torso are dis cussed.
