Применение спекл-корреляционного анализа для определения скорости кровотока

Optical methods based on the registration of speckle dynamics are widely used for the timely diagnosis of the microvasculature. This paper presents the results of the development of a laboratory model of a small-sized non-contact speckle sensor of the microvasculature, as well as the experimental technique. A speckle sensor model for determining the blood flow velocity in the microvasculature is presented. It may be the bases for creation of prototype sensor. The results of preliminary experimental studies of the possibility of monitoring blood microcirculation in the microvasculature using speckle correlation analysis are presented. During the experiments, a group of healthy volunteers aged 18-24 years are studied. The obtained results correlate with the results presented in the literature on the value of the determined blood flow velocity. The problems and prospects of speckle-correlation monitoring of the microvasculature in laboratory and clinical conditions are discussed.
