Abstract

The photoacoustic (PA) signal attenuation was affected by many factors in an imaging system. In this presentation, the factors lead to the signal attenuation and their characters were discussed based on tissue optics, acoustic transportation and detection in a long-focal-zone PA imaging system. A method to recover the detected PA signals was presented and employed to image a thyroid sample in vitro. The experimental results demonstrated that the method could be used to improve the imaging depth and quality in the PA system.
