In order to make the process of hemodialysis with good efficiency, we must always maintain and monitor arteriovenous fistula function. 80% or more frequent injections of arteriovenous fistula will develop, which led to the phenomenon of vascular stenosis squeeze generated, stenosis due to blood vessel blockage and can’t be dialysis treatment, there will be life-threatening. In order to maintain arteriovenous fistula blood flow, and attention must always keep monitoring whether the produce vascular stenosis phenomenon between hemodialysis patients and doctors important objective. This study use a non-invasive hyperspectral imaging technology, including the use of charge-coupled display different laser wavelengths. Using Matlab to transform image which format is JPEG into 1024*768 – 8bit matrix in order to be used by Labview for image handling, the goal of this research is to develop and apply particular the principle of hyperspectral imaging for early detection and real-time monitoring the status of narrowing blood vessel, which could increase the quality of clinical care.
