In this study, we propose and test a photoacoustic imaging system with a scanning mirror-based SAFT（SM-SAFT） for simple and fast data acquisition, without the need for a physical scan of the transducer. Photoacoustic images of hair phantoms acquired by SM-SAFT are demonstrated, serving as a proof-of-concept experiment to show the feasibility and potential of the proposed approach.展开更多
