Abstract

Light propagation in an n-layered model of the brain was investigated using solutions of the diffusion theory. A neural network was applied to study the inverse problem. The reduced scattering coefficient and the absorption coefficient of the brain were determined in a four-layered model. In addition, without knowing exactly the optical properties of the other layers we calculated the absorption coefficient of the brain in a four- and five-layered model.
