Practical improvements on photon diffusion theory: application to isotropic scattering.
Based on the analysis of an isotropic point source in an infinite, isotropically scattering turbid medium, we suggest several modifications to the well-known diffusion theory. Compared with standard diffusion theory these modifications, which require very little extra mathematics, lead to a substantially better approximation of the exact expressions. The improved expression gives reasons to reconsider the basic concept of time-resolved diffusion theory.
