超声调制光学层析成像为生物医学诊断提供了一种非常有前途的无创成像方法。通过这种技术，超声波束被聚焦到散射介质中，以提供精确的定位，同时对介质内的激光进行调制。基于高灵敏度的探测技术，我们开发了一种独特的反射式结构，它比现有的其他结构更方便和实用。此外，该配置还引入了一种新的方案来提高成像中的空间分辨率。对体模进行成像，以验证所提出配置的可行性。
Ultrasound-modulated optical tomography affords a very promising noninvasive imaging method for biomedical diagnosis. With this technique, an ultrasound beam is focused into a scattering medium to provide an accurate localization and, simultaneously, a modulation of laser light inside the medium. Based on the high-sensitivity detection technique, we have developed a unique reflective configuration, which was more convenient and practical than other existing configurations. Furthermore, the configuration also introduced a new scheme to improve the spatial resolution in the imaging. A phantom was imaged to validate the feasibility of the proposed configuration.
