The clinical diagnosis and treatment of patients suffering from brain abnormalities usually require exhaustive exploration of biomedical images. However, images of a single modality do not provide a set of information. The inadequacy of clinical information makes a biomedical image of single modality insufficient for use in clinical interpretation and diagnosis of disease. In general, information acquired from images resulting from different modalities is complementary in nature. Fusion of multimodal images can be achieved after registration of two images. Registration process takes care of two images getting into on single alignment considering any one of the image as a reference. There different types of registration methods are available. Rigid registration and non-rigid (deformable registration) are the two types of registrations. Rigid registration methods consider the only rigid structure, like boundaries and edges present in the images. Deformable registration method looks into the geometrical deformation present in the images. Considering the medical images, geometric deformation referred to the soft tissues behavior during the interventional procedure or due to the over a period of time changes takes place in the tissue. Deformable registration has become more important in recent days. Proposed article deal with the study on appropriate deformable registration for multimodal medical images
