AB  - Deformable image registration is the spatial mapping of corresponding locations 
      between images and can be used for important applications in radiotherapy. 
      Although numerous methods have attempted to register deformable medical images 
      automatically, such as salient-feature-based registration (SFBR), free-form 
      deformation (FFD), and demons, no automatic method for registration is perfect, 
      and no generic automatic algorithm has shown to work properly for clinical 
      applications due to the fact that the deformation field is often complex and 
      cannot be estimated well by current automatic deformable registration methods. 
      This paper focuses on how to revise registration results interactively for 
      deformable image registration. We can manually revise the transformed image 
      locally in a hierarchical multigrid manner to make the transformed image register 
      well with the reference image. The proposed method is based on multilevel 
      B-spline to interactively revise the deformable transformation in the overlapping 
      region between the reference image and the transformed image. The resulting 
      deformation controls the shape of the transformed image and produces a nice 
      registration or improves the registration results of other registration methods. 
      Experimental results in clinical medical images for adaptive radiotherapy 
      demonstrated the effectiveness of the proposed method.
