摘要 基于体素的配准方法中最有效的就是最大互信息的配准方法;该方法在计算互信息的时候,采用部分体积插值计算联合直方图,这样就无法避免出现的局部极值,有可能导致误配准。文中提出了改进的部分体积插值方法,有效地避免陷入局部极值,减少误配率。 The most efficient voxel-based method is maximization of mutual information (MI). It will introduce local maximum at in calculating joint histogram with conventional partial volume (PV) interpolation. An expand PV interpolation algorithm is proposed to avoid getting into the local maximum, it can reduce misregistration rate.
