| Abstract: | An integrative fast photoacoustic imaging system based on multi-element phase-controlled technique was developed, which integrated laser delivery, photoacoustic excitation and photoacoustic detection. The PA signals were received by the multi-element transducer array in a reflection mode, reconstructed by phase-controlled focus algorithm. The PA images of different depths of phantom lard and animal blood vessels of different diameters were obtained. The lateral resolution of the system was 0.5 mm, and the whole PA imaging time was less than 5 s. |
