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.

Photoacoustic tracking and registration in interventional ultrasound

According to some embodiments of the invention, a robot-assisted ultrasound system includes a first ultrasound probe, a robot comprising a manipulator arm having a tool end, and a second ultrasound probe attached to the tool end of the manipulator arm. The robot-assisted ultrasound system further includes a robot control system configured to control at least one of a position or a pose of the second ultrasound probe based on a contemporaneous position and pose of the first ultrasound probe, and an ultrasound processing and display system configured to communicate with at least one of the first and second ultrasound probes to receive and display an ultrasound image based on the first and second ultrasound probes acting in conjunction with each other.

Robot assisted ultrasound system

A virtual rigid body optical tracking system includes a virtual rigid body generator for projecting a virtual rigid body, wherein the virtual rigid body forms a pattern of light on a surface. The virtual rigid body optical tracking system includes an optical detection system for detecting the pattern of light, and a data processing system in communication with the optical detection system. The data processing system is configured to determine a position of the virtual rigid body generator based on the detected pattern of light.
