Distributed Scatter Model for computing diffuse reflectance of light from turbid biological media

We investigate whether a combination of steady-state diffusion theory with a distributed set of single scatter sources may describe the diffuse reflectance of light from tissue. We have compared the predictions of the single interaction model with the numerical results obtained by an exponentially weighted scatter source model and we have found a quite good agreement of the latter with Monte Carlo simulations over a wide range of the transport albedo.
