Medical image registration technology is the foundation of the medical image fusion and it is also the element of the image-based three-dimensional reconstruction.A medical image registration method was presented based on the feature points calculated by SUSAN operator.First,the corner points of two images were extracted with the SUSAN operator;then,the two feature points sets were matched and the matched feature point pairs were obtained through coarse matching and fine matching;Finally,the reverse mapping of the affine transformation were utilized to achieve image registration.The experimental results show that the medical image registration and good accuracy can be effectively achieved by using this method.
