Paper Abstract

A double-ring photoacoustic sensor to image and monitor blood content in tissue has been developed. This sensor has a very small opening angle. Using this sensor we are able to image artifical blood vessels, as well as vessels in a rabbit ear. Furthermore, the feasibility of in vivo imaging is demonstrated with a photoacoustic reconstruction of the joining of two palmar veins a few centimeter proximal to the wrist in a human arm.
