Measuring red blood cell velocity in microvessels by images correlation technique

Abstract

By means of a microscopic TV system with computer image processing equipment and a application program, the flow velocity of red blood cells can be quantitatively measured by spatial correlation detection as well as the change of the flow regime of microcirculation can be clearly observed on the monitor. This system not only reserves all the advantages of microscopic TV systems which are widely used in clinical detection now, but also can get satisfied measuring results by applying digitized processing on the images of microvessels to eliminate the background fluctuation and other disturbance signals which often lead to wrong results in the measurement of red blood cell velocity.
