Ultrasound Assisted Optical Imaging
Abstract
Two new diffusive optical imaging systems have been built for improved portability and shorter data acquisition time. We are conducting clinical studies simultaneously at University of Connecticut Health Center and Hartford Hospital with our optical imagers combined with commercial ultrasound. More than 60 patients have been recruited and image initial analysis has been made. Preliminary results have demonstrated the great potential of ultrasound assisted optical imaging in distinguishing malignant tumors from benign lesions. Image reconstruction algorithms based on finite element method have been investigated for better image quality. Novel pseudo-random bit sequence based spread spectrum system architecture is proposed for time-resolved diffusive optical tomography. We have validated the feasibility of such an approach by simulations and experiments. We are planning to use this new technology in our future system upgrade and modification, aiming at more accurate reconstructed values for optical properties of human breast tissues and higher spatial resolution.
