Comparison of four Monte Carlo methods for photon migration in biological tissues

摘要

We consider four different Monte Carlo methods, widely used in tissue optics, based on four different ways to build photons' trajectories. By means of numerical results we compare the temporal point spread functions calculated by the four methods for a wide range of the optical properties in the slab and semi-infinite medium geometry. Therefore, we show the statistical equivalence of the four methods and some of their convergence characteristics.
