Laser-Doppler Blood-Flowmetery Modeling by Monte Carlo Method

Abstract

Laser Doppler Flowmetery (LDF) is a noninvasive method to assess tissue blood flow. Previously published works have proposed a mathematical model for LDF and showed that there is a relationship between first moment of power spectrum and the velocity of moving blood cells (MBC's). Also researchers have studied this method by mathematical analyses in various aspects. In this paper a new model for LDF based on Monte Carlo method is proposed. We have shown that this new model is more flexible and provides a better agreement with the experimental results. For example this model represents the nonlinear relationship between the first moment of power spectrum and the blood cells velocity which is not seen in previous models.
