Abstract

Photoacoustic tomography (PAT) is a powerful medical imaging technique for medicinal diagnosis in that it combines the merits and most compelling features of light and sound to the biological tissue. It can be potentially used for the detection of the first-stage breast cancers and the blood vessel net-works in the deep depth of tissue. In this paper, a PAT experimental system constructed in our laboratory is presented by the use of 532nm wavelength light as an excitation source. By using this system, we demonstrated that it is feasible to image blood vessel networks in highly scattering ex vivo and in vivo tissue samples.
