Abstract
The central theme in developing models of light propagation in tissues is the accurate prediction of the spatial distribution of the photon or energy fluence. Diffusion theory has been widely used and applies mainly far from sources and tissue boundaries in highly scattering media. By contrast, Monte Carlo simulations are most successful in describing the behavior of the fluence near sources and boundaries, and can incorporate any absorption and scattering conditions. Thus, a hybrid model combining these strengths may provide an optimal approach to calculating the light fluence distributions in tissue. The elements of such a hybrid model are described and evaluated for different external light beam and interstitial optical fiber source geometries, using optical absorption and scattering coefficients which are typical of soft tissues in the red part of the visible spectrum.
