光声成像研究进展

Research progresses of photoacoustic imaging

本文阐述了光声成像的工作原理,光声信号的产生,传播和探测过程,并总结了光声成像的研究进展,包括时域光声成像和频率域光声成像的研究进展、以及各自的特点,为光声成像领域的研究起到一定的借鉴作用。分析认为光声成像技术有着其他医学成像技术没有的诸多优点,如高分辨率、高对比度、成像深度深等具有广阔的应用前景和较高应用价值,是未来生物医学领域最重要的实时医学成像技术之一,因此得到了国际上的广泛关注。

Photoacoustic imaging has obtained the widespread attention in the world due to its high resolution,high contrast and deep imaging depth etc. This paper describes the principles of photoacoustic imaging,the process of its generation,propagation and detection,reconstruction algorithms and its applications in clinical medicine,and also summarizes the progress of photoacoustic imaging,as well as their individual features. According to the analysis,photoacoustic imaging is thought to have many advantages,which other medical imaging techniques do not have,as well as a broad application prospect and high application value. And in the future,photoacoustic imaging will become one of the most important biomedical imaging techniques,and make outstanding contributions for the realization of real-time medical imaging.
