FIGURE 1. Standard FDG-PET/CT imaging protocol. The patient is positioned on a common patient handling system in front of the combined gantry. First, a topogram is used to define the co-axial imaging range (orange). The spiral CT scan (gray box) precedes the emission scan (green box). CT images are reconstructed on-line and used for the purpose of automatic attenuation correction of the corresponding emission data (blue box). Black and blue arrows indicate acquisition and data processing streams, respectively.
