Abstract

An automatic digital image processing technique for vasomotion analysis in peripheral microcirculation at multiple sites simultaneously and in real time, is presented. The algorithm utilizes either fluorescent or bright field microimages of the vasculature as input. The video images are digitized and analyzed on-line by an IBM RT PC. Using digital filtering and edge detection, the technique allows simultaneous diameter measurement at more than one site. The sampling frequency is higher than 5 Hz when only one site is tracked. The performance of the algorithm is tested in the hamster cutaneous microcirculation.
