Description
Summary:A prototype B-scan photoacoustic tomography system is developed. It integrates pumping fiber, ultrasound coupling medium, and a transducer array into a novel hybridized scanning head. By moving the scanning head a photoacoustic tomography can be obtained in the reflection mode. Concentration-adjustable glycerite is used as the ultrasonic coupling medium to match the ultrasonic velocities in tissues, reducing the acoustic reflection, eliminating the acoustic refraction, and rectifying the acoustic path difference. This system is used to image graphite phantom in tissue and human blood vessels. Our experimental results show that this integrative system has the potential for fast photoacoustic imaging.
