ABSTRACT
The wave properties of light propagating through a turbid medium tend to be averaged out after several scattering interactions. Consequently, the modeling of light propagation in turbid media can be simplified by ignoring the wave-like behavior. Therefore, it is acceptable to model the propagation of light through turbid media as a stream of particles, each with a quantum of energy (Ishimaru, 1987; Patterson et al., 1991; Wang et al., 1995). Under these assumptions, the radiative transport
