Abstract

Liver cancer represents a major health care problem in the world, especially in China and several countries in Southeast Asia. The most effective treatment is through tumor resection. To improve the outcome of surgery, a combination of preoperative planning and intra operative image guided liver surgery (IGLS) system has been developed at Pathfinder Therapeutics, Inc. The preoperative planning subsystem (Linasys® PlaniSight®) is user-oriented and applies several novel algorithms on image segmentation and modeling, which allows the user to build various organ and tumor models with anticipated resection planes in less than 30 minutes. The surgeons can analyze the patient-specific case and set up surgical protocols. This information in image space can then be transferred into physical space through our intra operative image guided liver surgery system (Linasys® SurgSight®) based on modifications of existing surface registration algorithms, allowing surgeons to perform more accurate resections after preoperative planning. This tool gives surgeons a better understanding of vessel structure and tumor locations within the liver parenchyma during the surgery. Our ongoing clinical trial shows that it greatly facilitates liver resection operation and it is expected to improve the surgery outcome and create more candidates for surgery.
