摘要
提出一种基于曲线形状匹配的头部磁共振图像自动配准方法,可实现预分割提取头部轮廓曲线、曲线形状特征提取及匹配和单层匹配结果的校正。实验证明在缺乏成像位置参数时,该方法可快速有效地成功实现头部磁共振图像的配准,特别是颅脑内部包含肿瘤的图像配准。
An automatic method of MR brain image registration based on contour shape match has been presented in this paper. It includes presegmentation to abstract head contour, contour shape feature abstract and match, and correction of single sli de match. Experiment results demonstrate its effectiveness for registration of T 1, T2 and PD images that lack of parameter of imaging position, especially for h ead images with tumor inside them.
