摘　　要：光声成像兼具声学成像和光学成像两者的优势,在生物医学领域表现出巨大的应用前景。实时成像、多模成像满足了对动态生理过程实时监控的需求,提高了临床诊断准确率,因而是生物医学成像技术发展的重要趋势。本项目拟集成光声-超声技术,在实现光声-超声双模实时成像的基础上,充分挖掘光声-超声两者物理效应的协同机制,解决两者不能独立解决时变复杂声学环境中的成像难题,实现两者不具备的新功能。本项目的研究顺应生物医学成像发展潮流,赋予光声-超声技术新的功能和应用空间,对于增强我国数字诊疗装备的技术竞争力具有积极意义。Photoacoustic imaging which takes the both merits of acoustic imaging and optical imaging shows great potential in biomedicine. Real-time imaging and multi-modal imaging, which satisfy the clinical requirements in real-time monitoring the dynamical physiological process and improving the diagnosis accuracy, are the important trends of biomedical imaging. The research group of this program will realize the photoacoustic-ultrasound dual-modal imaging by integrating the photoacoustic and ultrasonic techniques. By digging the cooperative effect between photoacoustics and ultrasound, the research group will try to challenge the imaging problems in the time varying and inhomogeneous tissues, which have not been solved by any signal techniques. This research program shows significant in improving technique competence of digital diagnosis and treatment equipment of China.
