Abstract

Ultrasound-modulated optical tomography (UOT) is a promising nondestructive technique for biological tissue imaging, and possesses both high sensitivity of optical imaging and good spatial resolution of ultrasonic imaging. In this paper, ultrasound-modulation of near infrared light is used to detect foreign bodies buried in turbid media. Experimental resultsshow that there is a linear increasing relationship between the modulation depth of acousto-optic signals andtheabsorption and scattering coefficients of turbid media. The position and shape of the foreign body (scatterer and absorber)buried in the tissue simulation sample can be reconstructed by the acousto-optic signals in UOT, and the strengthofscattering objects and absorption objects can be detected. But the scattering objects and absorption objects aren’t distinguishable in the imaging.
