Ultrasound Guidance for Surgical Interventions
This project is concerned with investigating the use of ultrasound imaging as a comprehensive interventional surgical guidance platform. Optical tracking technology is used to record the physical position of the ultrasound probe in the operating room in order to facilitate registration of intraoperative ultrasound images to the patient’s preoperative imaging. The surgical problems which the project attempts to address include correcting images for tissue compression exerted by the ultrasound probe, detection of tumor borders, and evaluation of ultrasound strain imaging as an intraoperative contrast mechanism. Our combined approach of tracking, registration, and biomechanical modeling is aimed providing the surgeon with accurate subsurface information to aid in decision-making during image-guided interventions.
