Human blood flows are highly susceptible to physical and health conditions. Hence quantitative evaluation of blood flow helps the physical check up of individuals. However, the most convenient method is taking a blood sample, which can only examine ex vivo blood condition. We developed digital high speed video capillaroscopy to observe the capillary loops of blood vessels in the finger skin nail fold, of which blood flow can be easily visualized. We discuss the optimal selection of both light source and finger holder, in order to obtain images with both clearer contrast and less blur. We found that the combination of both the halogen light with focusing attachment and brush holder provides satisfactory results with qualitative evaluation by using image processing tools of MATLAB.
