A path integral model of light scattered by turbid media

摘要

Imaging techniques involving transillumination require detailed knowledge of radiation path(s) between source and detector. When imaging with near infra-red in tissue this is particularly problematic due to the high scattering cross section. The population of 'direct path' photons is so small that information must be gathered from the much larger (but still small) population of 'snaked path' photons.
