Technique for Medical Image Geometrical Registration Based on ICP Algorithm
Bin Li · Jisuanji gongcheng · 2003
Geometrical registration is an important research field in medical image. The goal of medical image registration is to establish a common reference frame between pre-surgical and intra-surgical 3-D data sets. This paper presents an ICP(iterative closest point ) algorithm based on contour feature. According to the example of femur model,it realizes three parts of geometrical registration:establishing pre-operative model,selecting intra-operative data sets,and programming ICP algorithm.
