Monte Carlo

The most efficient tool for studying light propagation in biological tissues in different optical experimental arrangements is the Monte Carlo (MC) method. It is based on calculation of trajectories of a large number of photons randomly propagating in a scattering medium with subsequent statistical analysis of the obtained data. This method is able to account for different scattering phase functions as well as for the multilayered structure of the considered medium and various configurations of source and detector units.

Our team has a wide experience in MC simulations. We have developed our own MC-based algorithm of light propagation in multilayered media containing structural inhomogeneities and implemented it on a multiprocessor platform with parallel architecture using MPI (Message Passing Interface) technology. The developed program was used for simulation of a number of techniques, in particular, OCT and DOCT signals, signals of diffuse reflectance with spatial and temporal resolution, alteration of tissue optical properties with nanoparticles.


Typical photon trajectories in three-layer medium. Upper and bottom layers are transparent (glass), middle layer is scattering (μs = 15 mm-1, g = 0.7). The probing radiation is shown with an arrow.
