Multi-modality images can provide comprehensive information for clinical diagnosis. In this study, a registration method for cardiac PET and MR images was proposed by combining global registration and local registration. During global registration, axial PET and CT images were transformed to short axis with MR-survey as link. Then local registration was performed between PET/CT and MR-cine images, it was found that using the fusion of PET and CT images performed better compared with that only using a single modality image.
