Paper Abstract

A technique has been developed to simultaneously acquire ultrasound and photoacoustic (PA) images base on a linear transducer array. The system uses conventional ultrasound for rapid identification of potential target(s). Once a target is identified, the ultrasound echo and PA signals can be simultaneously obtained with optimized excitation and signal collection sequence. The corresponding ultrasound impedance and optical absorption images can be reconstructed with an algorithm similar to that used for conventional ultrasound imaging. The approach can effectively reduce the artifacts associated in conventional filter back-projection algorithm used in PA imaging by linear scanning. The technique provides a potential approach for practical applications.
