title: Optical diffusion imaging: a comparative numerical and experimental study.
abstract: We present a low-cost photodiode-LED apparatus for making broadband frequency domain photon migration measurements. We compare measured data to finite-difference frequency domain solutions of the diffusion approximation of the Boltzmann transport equation. Specific comparisons include the influence of boundary conditions on simulations and the effect of finite source size on resolution.
