Abstract

In this paper, we present a reconstruction algorithm for backward mode optoacoustic imaging. The algorithm is developed from the optoacoustic wave equations and takes advantage of the simplification associated with line focusing, which is implemented with a synthetic aperture focusing and adaptive weighting method. Computer simulations and experiments were conducted to verify efficacy of the algorithm. Performance differences between numerical simulations and the experiments will be presented and discussed.
