Outline of Final Research Achievements

We conducted a study to realize the imaging system of the blood vessel in order to detect the abnormality of the blood vessel structure in the arteriovenous fistula for hemodialysis.
We have developed the measuring system to observe the arteriovenous structure that is non-invasive and compact utilizing the diffuse light in the body tissue positively based on our previous research on the optical bioinstrumentation. We have developed the image processing algorithm to depict the structure in the blood vessel and verified it with the experiment with the phantom. Moreover we have presented the possibility to depict the changes of the blood vessel property in combination with spectroscopic technology. Herewith, we have shown the validity of our proposed system.
