Abstract: CFG image analysis system digitizes a image coming from a video camera then to show this image on a video monitor.It can make multiple quantitative analysis to image structure.In our experiment,first,the myocardial ischemia model is completed,making the immunohistochemical staining of creatine kinase on pathological sections, then to measure the red,green and blue color data of every pixels of these section with CFG image analysis system.The results showed that the color data is prominent lower than that normal after 1 hour ischemia;the decreased degree of color data is marked accompanying by the increased ischemic time;the area of color data decrease become larger accompanying by the increased ischimic time.CFG image analysis has advantages of rapid and precise.

Key words: CFG image analysis system, myocardial ischemia, creatine kinase
