| Research Abstract |
In this study, it is demonstrated that dynamic observation and analysis of peripheral vessels underneath skin surface by sweat-source optical coherence tomography. In the experiment, we developed OCT system which has the high image resolution of 5μm with the high image acquisition rate of 50 frames/ s. In vivo observation for dynamic functional analysis not only small arteries and veins of human fingers but also arteriole and venule were demonstrated. In particular, we developed the solid image of the arteriole and the venule by the 3-dimensional OCT images. Furthermore, simultaneous measurement of dynamics of the physiological function of peripheral vessels for the activity of the autonomic nervous system were demonstrated.
