Data-driven phase-matched PET/CT: A solution for axial location-dependent respiratory phase in CT

1420 null Introduction: null null Respiratory motion introduces motion blurring and attenuation and activity mismatch artifacts in PET/CT scans. In a free-breathing PET/CT scan, the data-driven approach allows the acquisition of respiratory information and subsequent motion compensation in the PET images. The 3D CT image is usually scanned prior to the PET scan, and the CT image is also affected by respiratory motion. Different axial positions...
