基于轮廓的多模态医学图像配准方法

here are some problems in Multi-modal image registration method based on gray mutual information, such as poor robustness and lower registration accuracy. So a multi-modal medical image registration method based on contours is proposed in this paper, which is based on mutual information and using the spatial information that the same organ in different modal contours have similarities. First, get the outline map R'、F' of the R、F which is subject to registration through morphological method, then using contour mutual information in image registration. Experimental results show that the method proposed in this paper can realize multi-modal medical image registration robustness and accurately.
