Notes:
A fast photo-acoustic (PA) imaging system was developed and tested on phantomsample, which consists of an acoustic lens,a multi-element linear transducer array, and the peakdetection circuit. The multi-element linear transducer array consists of 64 elements. By utilizing anacoustic lens, the PA signals generated from the sample are imaged and detected by a multi-elementlinear transducer array, which directly changes the PA signals into the homologous electronicsignals. Thus we can map the image more rapidly, with the peak detection circuit, which wasdesigned specially. Compared to other exiting technology and algorithm, the PA imaging systembased on an acoustic lens and the peak detection technology was characterized with speediness andreal-time. The images reconstructed in this experiment have high definition and resolution,andmay have potential for developing an appliance for clinical diagnosis
