Abstract

Ultrasound-modulated optical tomography affords a very promising noninvasive imaging method for biomedical diagnosis. In this technology ultrasonic beams are focused into a scattering medium to provided accurate localization and simultaneously modulate light inside the medium. The detected ultrasound-tagging photons will bring the information of the characteristics of the medium. Based on the high-sensitivity detection technique, we develop a unique reflective configuration that the ultrasound and light are kept coaxial, which is more convenient and practical than other configurations. A completely absorbing object imbedded in a tissue is imaged using the corresponding experimental setup designed by us which is based on the configuration.
