Abstract

An image analysis system is described for the measurement of the blood velocity and the flow profile in microcirculation. It uses a super-high-speed video tape recorder (100 frames/s) and the image gradient method. The measured mean red blood cell velocity of the microvessels (venules having diameters of 15-40 μm) is 0.7-4.0 mm/s and the measured mean flow volume is 0.7-5.0 × 10^-3 mm³/s. A flow chart of the image processing algorithm and results which show the velocity vectors and temporal change of the red blood cell velocity are given.
