Ultrasound Assisted Optical Imaging
Abstract
A DC and a frequency-domain near-infrared diffusive imaging systems have been built, tested, and calibrated. Optimal numbers of optical sources and detectors were found from computer simulations. Phantom studies have demonstrated that combined ultrasound/optical imager benefits from high spatial resolution of ultrasound and improved accuracy of reconstructed maps of optical properties. A novel image reconstruction algorithm has been proposed and implemented. It reconstructs lower orders moments of targets from limited information from a diffusive system, and is more robust than conventional iterative algorithms. Clinical study will be started soon, which will eventually test the effectiveness of this new technique for breast cancer detection.
