Abstract
The present paper is concerned with the simulation, by random sampling, of the multiple scattering of photons for the purpose of solving near-IR radiation in complex multi- layer highly scattering media, which represent the structure of human skin in a simplistic manner. Direct weight Monte Carlo algorithm is imitating transport of photons between source detector areas by letting the photons carry out a random walk, each step of which is taken into account that provides information about time of photon presence in each layer of a medium. The last one makes it possible to estimate the depth sensitivity and the degree of spatial localization offered by fiber-optics probes of various geometries. Discussion of these limitations and potential possibilities of our simulation of skin model is given as well as a new suggestion for simulation of complex multi- layer tissues.
