Ultrasound detection is one of the major components of photoacoustic imaging systems. Advancement in ultrasound transducer technology has a significant impact on the translation of photoacoustic imaging to the clinic. Here, we present an overview on various ultrasound transducer technologies including conventional piezoelectric and micromachined transducers, as well as optical ultrasound detection technology. We explain the core components of each technology, their working principle, and describe their manufacturing process. We then quantitatively compare their performance when they are used in the receive mode of a photoacoustic imaging system.
超声检测是光声成像系统的主要组成部分之一。超声换能器技术的进步对光声成像向临床应用的转化具有重大影响。在此，我们概述了各种超声换能器技术，包括传统的压电换能器和微机械加工换能器，以及光学超声检测技术。我们解释了每种技术的核心组件、其工作原理，并描述了其制造过程。然后，我们定量比较了它们在光声成像系统接收模式下的性能。
