中文摘要:
      生物超声(US)、光声(PA)和磁声(MA)成像均以超声波作为载体,将其结合可获得生物组织的组合图像,充分发挥各成像手段的优势。与单一成像技术相比,联合成像具有更好的分辨率及更高的对比度和敏感度,可更精准地定位病变组织,并辨识出其形态和成分。本文对光声—超声、磁声—超声及磁光声联合成像,尤其内窥式联合成像的研究进展及应用现状进行综述。
英文摘要:
      Biological ultrasonic (US), photoacoustic (PA) and magnetoacoustic (MA) imaging techniques had similar imaging principles and complementary characteristics. Combined US, PA or MA imaging can provide joint images of biological tissues which present complementary information for more comprehensive characterization of tissues in contrast to single imaging technique. The pathological tissues could be precisely located and their morphology and composition could be accurately identified. This review presented current progresses in combined PA—US, MA—US and US—PA—MA imaging techniques, espeically endoscopic imaging, focusing on the technical aspects of integration and their applications in biomedicine.
