Paper Abstract

Acousto-photonic imaging (API) is a new approach in biomedical imaging that combines diffuse imaging by photon density waves (PDW) and light "tagging" inside the tissue by focussed ultrasound. This light "tagging" enables 3D optical imaging with mm resolution in tissue limited only by the geometrical extent of the ultrasound focus and the signal to noise ratio. We discuss some possible mechanisms of light "tagging" and its dependance of different parameters. We present several phantom measurements which investigate advantages and disadvantages of API against PDW. The main advantage of API is the possibility of real 3D imaging while its biggest disadvantage is the poor light intensity from deeper regions.
