Abstract
A combined ultrasound and near infrared (NIR) diffused light imaging system includes a combined ultrasound and NIR light probe operatively connected to an ultrasound imaging system and an NIR diffused light imaging system. The combined ultrasound and NIR light probe comprises ultrasound transducer elements distributed in a rectangular matrix. Each element works in pulse-echo mode to provide spatial images of tissue at various depths. The optical system includes laser diode light sources and photomultiplier tube detectors. Measurement can be done at multiple source-detector positions to develop image-reconstruction schemes to determine absorption and scattering coefficients as well as oxygen and blood concentration of the tissue volume at various slice depths. A display device provides co-registration of acoustic and optical images output by the ultrasound and NIR diffused light imaging systems.
