Figure 5

Examples of motion management strategies for two patients receiving PET/CT-guided radiotherapy. The top row des a patient whose baseline diagnostic factors indicate a highly period tumor motion and respiratory pattern, suitable for respiratory motion-tracked PET/CT and motion-tracked radiotherapy. The bottom row illustrates a patient whose chaotic respiratory pattern makes them suitable for PET/CT and radiotherapy under active breathing control (ABC) and prospective respiratory gating during a finite time period. Figure adapted from Liu et al. and Chin et al.[29, 65, 76].
