光声成像技术及其临床应用

Photoacoustic Imaging and Its Clinical Applications

  • 摘要: 光声成像作为一种新兴的生物医学成像技术,以光声效应为成像基础,结合光学成像对比度高、光谱特异度好、声学成像空间分辨率高和穿透力强的特点,具有广泛的临床应用前景。本文从光声成像基本原理、成像模式、在临床医学领域的应用前景以及目前存在的技术局限等方面进行详细介绍。

     

    Abstract: Photoacoustic imaging(PAI) is a state of the art biomedical imaging technique with the potential of wide application. Based on the photoacoustic effect, PAI combines the advantage of optical imaging as high contrast and spectroscopic specificity with the advantage of ultrasonography as high spatial resolution and deep penetration. This paper introduced the latest progress in PAI, which contains the fundamentals of photoacoustic imaging, the improvement in detecting modes of images, and the most promising clinical applications. The limitation of PAI has also been discussed.
