Methods of Mesh Generation for Biomagnetic Problems

摘要

The paper deals with techniques used for creation of realistically shaped models applied in solution of forward and inverse biomagnetic problems. An application of parametric Fourier representation of closed polygons to generation of boundary element meshes is described. It enables to reduce the number of generated elements with preserving the essential information about an object shape. A simple 2D-finite element mesh generator is also presented. Finally, an example of calculations of electric and magnetic fields generated by a current dipole placed in a human brain is given.
