Abstract

We describe an imaging technique that combines near-infrared diffuse optical tomography and reconstructive ultrasound tomography. With the combined approach, we experimentally demonstrate that 2-3mm size targets embedded in a 5cm diameter background can be reconstructed quantitatively in terms of the absorption and reduced scattering coefficients of the target, whereas it is impossible to optically resolve the targets without the ultrasonic guidance.
