ABSTRACT:
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 data with strain gauge levels being recorded, optimal gating criteria are calculated based on the strain gauge levels, and a second CT scan is then performed with triggering in accordance with the optimal gating criteria.
