抄録

Registration is a technique for corresponding between a pre-operative planning space and an intra-operative surgical space. It is often used in computer-integrated surgical systems, such as surgical navigation systems and surgical robots. One of most foundational registration methods is point-pair registration. We propose a method for estimation of most appropriate sampling-point set based on bone-surface shape analysis. The method consists of two steps; the first step is an estimation of point sampling error distribution from the bone surface, and the next one is an optimization of sampling-point set by using a computer simulation of point-pair registration. The result shows the effectiveness of this method.
