| 摘 要： | 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 hnprove the spatial resolution in the imaging. A phantom was imaged to validate the feasibility of the proposed configuration.
