A stochastic differential equation-based Monte Carlo simulation to model light propagation in dynamic turbid media

Abstract

We present a novel approach that combines Monte Carlo simulations to propagate photons in a turbid media having the dynamics modelled using stochastic differential equations, resulting in simulating diffuse laser speckles for in-vivo blood flow imaging applications. The proposed method allows to model the tissue dynamics with a pre-defined probability density function and spatially varying autocorrelation.
