Development of real-time navigation system for laparoscopic hepatectomy using magnetic micro sensor.

Background: We report a new real-time navigation system for laparoscopic hepatectomy (LH), which resembles a car navigation system.

Material And Methods: Virtual three-dimensional liver and body images were reconstructed using the "New-VES" system, which worked as roadmap during surgery. Several points of the patient's body were registered in virtual images using a magnetic position sensor (MPS).
