Abstract

Optoacoustic Tomography (OAT) is a hybrid imaging modality that combines the advantages of both optical imaging and ultrasound imaging techniques. Most existing reconstruction algorithms for OAT assume pointlike transducers, which may result in conspicous image blurring and distortions in certain applications. In this work, a new imaging model that incorporates the transducer response is employed for image reconstruction. Computer-simulation studies demonstrate that the new reconstruction method can effectively compensate for image resolution degradation associated with the transducer response.
