This paper presents a new attempt to modify the boundary element method
formulation of the diffusion approximation to the radiative transport
equation, to model
the propagation of photons in a turbid medium. Both diffuse and
sources are considered in the formulation of the BEM. A geometric
introduced to handle the forward scattering property of the medium in
the case of a
collimated and highly directional light source normally incident upon
boundary. This function is included in the boundary element formulation
to allow a
more realistic representation of anisotropic scattering than the
where fictitious buried isotropic point sources are introduced in the
tissue. The results of
the modified BEM solution are compared against corresponding Monte
and show very good agreement.
