Abstract :
A boundary element formulation for biomagnetic problems is described. The use of an analytical element integration and tuning of the boundary element method (BEM) forward solution for implementation in the inverse problem algorithm results in a far better relationship between accuracy and computational effort. The computational accuracy of the realistic heart and torso model compared with the simplified models commonly used in the literature is shown
