Photon transport theories in Physics,<unk> ine, and Statistics (such as the Monte Carlo method), are commonly used to model light propagation in tissue. The<unk>  to a pencil<unk>  incident on a<unk> <unk> m are referred to as Green's functions or impulse<unk> . Photon transport methods can be directly used to compute<unk> -beam<unk>  by distributing photons over the cross section of the<unk> . However,<unk>  can be used in certain cases to improve computational efficiency.
