Zusammenfassung:The invention discloses a PET/CT image fusion automatic labeling method. The method comprises the steps of: 1, preparing a CT image and a PET image; 2, automatically registering the CT image and the PET image through feature points; 3, after registration, carrying out automatic positioning on the PET image according to the SUV value, and finding out an region with violent molecular activity in thePET image; 4, carrying out region growth on a region with violent molecular activity in the PET image through a region growth method so as to realize labeling of a molecular active region; 5, fusingthe CT image and the PET image according to requirements, labeling the outline in the PET image into the CT image, and finally generating a PET/PC fusion image and a labeled CT image. After the CT image and the PET image are fused, the defects of the PET image and the CT image when the PET image and the CT image are used independently are overcome; meanwhile, the lesion focus structure and the functional metabolism conditi
