Abstract

The least scattered photons that arrive at a detector through the highly scattering tissues have the potential for imaging internal structures, functions and status with high imaging resolution. In contrast optical diffusing tomography is based on the use of the late arriving photons, which have been diffusely scattered, leading to very low imaging resolution. A good model of the early arriving photons, i.e. the least scattered photons may have a significant impact on the development of imaging algorithms and the further understanding of imaging mechanisms within current high resolution optical imaging techniques. This paper describes a vertex/propagator approach, which attempts to find the probabilities for least scattered photons traversing a scattering medium, based on analytical expressions for photon histories. The basic mathematical derivations for the model are outlined, and the results are discussed and found to be in very good agreement with those from the Monte-Carlo simulations.
