Paper Abstract

Photon transport in complex biological tissues is most accurately predicted via Monte Carlo (MC) modeling methods, which often require lengthy computation times. In this report, a semi-analytical technique (henceforth referred to as PI-scaling) was derived that combines MC simulation, absorption scaling, and path integrals (PI) to rapidly reconstruct time-resolved reflectance from the surface of bilayered epithelial tissue models. Comparisons to forward MC simulations indicated that the PI−scaling method was accurate to better than 10% for tissue models where the optical properties of the top layer did not greatly influence the time-resolved reflectance. Employing such a method should provide a novel solution to the first step of the problem of rapid simulation of time-resolved reflectance of photons in layered tissues.
