Photoacoustic imaging—a hybrid biomedical imaging modality finding its way to clinical practices. Although the photoacoustic phenomenon was known more than a century back, only in the last two decades it has been widely researched and used for biomedical imaging applications. In this review we focus on the development and progress of the technology in the last decade (2011–2020). From becoming more and more user friendly, cheaper in cost, portable in size, photoacoustic imaging promises a wide range of applications, if translated to clinic. The growth of photoacoustic community is steady, and with several new directions researchers are exploring, it is inevitable that photoacoustic imaging will one day establish itself as a regular imaging system in the clinical practices.

光声成像——一种混合生物医学成像模式，进入临床实践。尽管光声现象早在一个多世纪前就已为人所知，但仅在过去的二十年中，它才被广泛研究并用于生物医学成像应用。在本次审查中，我们重点关注过去十年（2011-2020 年）该技术的发展和进步。从变得越来越用户友好、成本更便宜、尺寸更便携，光声成像有望在临床应用中得到广泛的应用。光声社区的发展是稳定的，随着研究人员正在探索几个新的方向，光声成像不可避免地有一天会成为临床实践中的常规成像系统。
