Abstract

An automatic digital image processing technique for simultaneous vasomotion analysis in peripheral microcirculation at multiple sites and in real time is presented. The algorithm utilizes either fluorescent or bright field micro-images 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 sampling frequency is higher than 5 Hz when only one site is tracked and decreases as the number of sites is incremented. Performance of the algorithm was tested for a hamster cutaneous microcirculation model.

摘要

本文提出了一种自动数字图像处理技术，用于实时同时分析多个部位外周微循环中的血管运动。该算法将脉管系统的荧光或明场显微图像作为输入。视频图像通过数字滤波和边缘检测在IBM RT PC上进行数字化和在线分析。当只跟踪一个部位时，采样频率高于5Hz，随着部位数量的增加而降低。该算法的性能在仓鼠皮肤微循环模型上进行了测试。
