Application of Micro Electro Mechanical System (MEMS) Technology in Photoacoustic Imaging

Photoacoustic imaging (PAI) is a new biomedical imaging technology that provides a mixed contrast mechanism and excellent spatial resolution in biological tissues. It is a non-invasive technology that can provide in vivo anatomical and functional information. This technology has great application potential in microscopic imaging and endoscope system. In recent years, the development of micro electro mechanical system (MEMS) technology has promoted the improvement and miniaturization of the photoacoustic imaging system, as well as its preclinical and clinical applications. This paper introduces the research progress of MEMS technology in photoacoustic microscope systems and the miniaturization of photoacoustic endoscope ultrasonic transducers, and points out the shortcomings of existing technology and the direction of future development.
