Paper Abstract

In this paper, we have constructed an integrative fast photoacoustic (PA) imaging system for fast photoacoustic imaging, which includes a fiber, ultrasonic coupling medium, and a multi-element linear transducer array (MLTA). The PA signals were received by the MLTA in a reflection mode arid collected by a computer, reconstructed by limited-field filtered back projection algorithm. The PA images of different depth of phantom and animal blood vessels of different diameters were obtained. The lateral resolution of the system was 0.2mm. It would provide a new approach to tissue functional images in vivo and may have potentials in developing into an appliance for clinic diagnosis of disease.
