Fast photoacoustic imaging systems,based on rotating multi-element linear transducer array,can improve the effect of asymmetric projection and reconstruct the photoacoustic image of complex absorbers.The simulation and experiments of photoacoustic images of rotating multi-element linear transducer array demonstrated that this kind of system could reconstruct images indicating the optical absorption distribution of absorbers.It will provides a novel and effective photoacoustic imaging approach for clinic diagnosis of neoplasm and tissue functional imaging in vivo,and has potential to be developed into a practical apparatus.
