Contour-based Rigid Registration of Multimodal Medical Images
基于轮廓的多设备医学图象的刚性配准

In this paper,a contour based rigid registration method of multimodal medical images is pvesented. Based on the semiautomatic search of contour, by using iterative algorithm of closest points to find corresponding points, the cost function is minimized and a best transformation can be obtained, so that the images are registered precisely. Depending on the strategy of choosing initial transformations many a time,the local minimum problem in process of iterative detection have been solved. This method is proved to be effective on registration of multimodal medical images in our experiment.
