Abstract
The authors have been developing a surgical robotic system for scaphoid fracture reduction. The system consists of a surgical planning software to plan the position and orientation of wire insertions and a robot to assist the wire positioning. For achieving the robotic surgery, registration process is required. One of promising methods for registration is the method which employs a 3D deformable model of bone surface and deforms it by using several 2D X-ray images. In this paper, the authors proposed a fast method of X-ray fluoroscopic position measurement for bones. The authors evaluated the computation time and discussed by compared with a conventional method.
