Abstract

Assessment of microcirculation is essential in evaluating the tissue condition after injury, surgery, or any vascular disease which can be performed via Laser Doppler flowmetry (LDF). LDF is a technique that uses monochromatic light to detect the shift in frequency of the light scattered back from moving scatterers in tissues. In the present work, Doppler frequency shift is calculated by Monte Carlo simulations of light-tissue interactions. The simulated results enable us to quantify the velocity of flow which could be verified using in-vitro flow models.
