Abstract

Optoacoustic imaging is an imaging technique based on the time-resolved arrival of sound waves at an array of pressure transducers on the tissue surface, where the sound waves were generated by thermoelastic expansion of optically absorbing objects within the tissue when heated by a pulsed laser. This paper discusses the time-resolved pressures and velocity potentials create by pulsed laser irradiation of absorbing objects of varying shape, as well as the process of back-projection of such data to create an optoacoustic image of the distribution of absorbing objects.
