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 devel-opment 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 appli-cations. This paper introduces the research progress of MEMS technology in photoacoustic micro-scope systems and the miniaturization of photoacoustic endoscope ultrasonic transducers, and points out the shortcomings of existing technology and the direction of future development.
