Abstract

The determination of photon migration path is important for both near infrared spectroscopy and optical imaging. Time resolved measurement enables one to restrict the volume of tissue sampled since for instance, the early detected photons in a homogeneous medium tend to have migrated along the straightest line between the source and detector. In this study the distribution of time-resolved photon migration paths in a heterogeneous scattering media which includes a non-scattering layer is investigated by Monte Carlo simulation. In a heterogeneous concentric circle model, the path distribution of the earliest detected photons lies along the boundary of the non-scattering layer whilst the distribution of photon migration paths for later arriving photons indicates penetration into deeper regions.
