Abstract

For transcutaneous imaging of arteriovenous fistula in dialysis treatment, we have developed a technique to improve the transillumination image. In this technique, we obtain an appropriate point spread function (PSF) using a fluorescent source implanted near the fistula inside the body. The effectiveness of the proposed technique was examined in the experiment using the model phantom with known internal structure. The possibility to detect the diameter-change in blood vessel by suppressing image deterioration caused by the scattering effect was confirmed. The applicability to animal tissue was also verified in the experiment.
