Photoacoustic computed tomography (PACT), also known as optoacoustic tomography, is an emerging imaging technique that holds great promise for biomedical imaging. PACT is a hybrid imaging method that can exploit the strong endogeneous contrast of optical methods along with the high spatial resolution of ultrasound methods. Similar to X-ray CT or MRI, PACT is a computed imaging modality that utilizes a reconstruction method for image formation. In this talk, we provide an overview of image reconstruction methods for PACT that have been proposed over the past 25 years. This review will include an overview of classic backprojection-based methods as well as modern optimization-based approaches to image reconstruction.
