Incorporating connected region labelling into automated image registration using mutual information

摘要: The information theoretic measure of mutual has been successfully applied to multi-modality medical image registration for several applications. There remain however; modality combinations which derived from the occurrence intensities alone does not provide a distinct optimum at true registration. authors propose an extension technique through use additional channel supplying region labelling information. These labels can specify simple regional connectivity or express higher level anatomical knowledge, be images being registered. show how extended include labelling, and demonstrate effectiveness this MR PET pelvis.
