摘　　要：光声成像的出现拓展了生物医学成像技术在细胞、组织和活体中的应用,从而监测复杂内环境中的多种生理过程。通过加入时间维度或进行多光谱成像,可以获得更丰富的组织信息,实现对目标形态结构和功能成分的定性和定量分析。对4维(3维和时间或3维和光谱)、5维(3维和时间、光谱)光声成像技术及光声光谱解混技术的研究进展进行了综述,预测临床应用前景并总结出目前存在的问题,展望了未来可能的发展方向。The emergence of photoacoustic imaging has expanded the application of biomedical imaging technology in cells,tissues,and living organisms to monitor a variety of physiological processes in complex internal environments.Photoacoustic imaging is essentially 3-D imaging,involving three spatial dimensions.By adding time or frequency dimensions,richer tissue information can be obtained,enabling qualitative and quantitative analysis of target morphological structures and functional components.This article reviews the research progress of 4-D(3-D+time or 3-D+spectrum),5-D(3-D+time+spectrum)photoacoustic imaging technology and photoacoustic spectral unmixing technology.and The current problems were summarized.The clinical application prospects and possible development directions in the future were predicted.
