Abstract
An ultrasound imaging system having real-time tracking and image registration includes a fiducial-marker system comprising an ultrasound transmitter structured to provide a localized ultrasound pulse at an optically observable localized spot on a body of interest. The system further includes an optical imaging system, a two-dimensional ultrasound imaging system, an optical image processing system, and an ultrasound image processing system. The ultrasound imaging system further includes a registration system configured to communicate with the optical image processing system and the ultrasound image processing system to receive information, the registration system being further configured to determine a coordinate transformation that registers the optical image with the two-dimensional ultrasound image based at least partially on information concerning the spatial locations determined for the combined ultrasound and optical fiducial marker observed in the optical image and in the two-dimensional ultrasound image.
