Abstract

The forward model in this work is based on the frequency- dependent diffusion approximation. The diffusion approximation is solved using the Finite Element Method with the Robin Boundary condition. The model is 2D, with a circular domain simulating the cross section of a limb. The meshes are generated with FIDAP, a computational fluid dynamics package. The diffusion matrix is solved using Cholesky decomposition, and results on the boundary for a modulated source include AC and DC data for a given set of optical parameters.
