A method for combined computed tomography (CT) imaging and positron emission tomography (PET) imaging uses respiration-gated CT imaging in which the optimal criteria for CT scan gating are determined after the PET scan has been performed. After acquisition of first CT scan image data and PET scan image...http://www.google.com/patents/US8060177?utm_source=gb-gplus-sharePatent US8060177 - Registration of computed tomography (CT) and positron emission tomography (PET) image scans with automatic patient motion correction
