For computation of forward and inverse solutions in bioelectromagnetism, digitized models of the associated volume conductor (human torso, human head) are required. Often a piecewise homogeneous model considering internal inhomogeneities (e.g. the lungs and the cavities of the heart; the skull and the cortex) is build up from MRI scans. In order to provide an explicit and compact representation of anatomical surfaces a semiautomatic meshing procedure has been developed. In a first step point clouds of the surfaces which have to be modeled are extracted manually from the MRI-scans. Then those surfaces are approximated by a double Fourier series or Legendre polynomials in a second step and the Boundary Element mesh is generated automatically.
