A study of blood flow in microvessels using biospeckle dynamics

Abstract  Hydrodynamic properties of blood flows in small microvessels and the patterns of scattering of focused laser beams in such flows were studied. The processes of formation of dynamic biospeckles are considered. The relationship between the optical parameters and hydrodynamic characteristics of blood microflow are analyzed. A new method is proposed for measureming the plasma rate in small microvessels with the use of in vivo microscopy in combination with speckle microscopy.
