Abstract

The early photons that arrive at a collector through a large thickness of tissue have potential for imaging internal organ structure, function, and status with improved image resolution relative to late arriving photons which have been diffusely scattered. Calculation of early photon arrival at a collector after transport through large tissue thicknesses is difficult, yet a comparison of predicted vs measured transmission is at the heart of imaging algorithms. The Path Integral description of light transport offers an approach toward such calculations. The method describes the movement of photons as particles undergoing collisions in a scattering medium based on the Brownian motion formalism of Feynman and Hibbs. This paper presents a basic introduction to the Path Integral description of photon transport and discusses the constrained classical path for describing the most probable path of a photon and the unconstrained classical path for describing the group path of an ensemble of photons.
