Non-rigid registration of monomodal image often takes an important role in image-guided radiotherapy and surgery. Viscous fluid model is widely used to enforce the topological properties on the deformation, and thus constrain the enormous solution space. Intensity-based method is popular in non-rigid registration, but it is sensitive to intensity variations. In this paper, we develop a new algorithm...
To register pre-operative MRI/CT images with intra-operative ultrasound images based on the vessels visible in both of the modalities, we presents a non-rigid registration method of multimodal medical images based on free form deformation was proposed. When the images are aligned, the centerline points of the vessels in one image will align with the intensity ridge points in the other image. Rigid...
