GTV DVH curves from various static respiratory phases (0%, 20%, 50%, and 90%) and the 4D cumulative dose for Case 2. The GTV was large (159.1 cm3) in relation to the tumor motion (1 cm). This is in contrast to Case 1, which had a similar range of tumor motion, but for a tumor which measured only 12.5 cm3. Consequently, the DVH curve for the average dose does not differ much from the static DVH curves (Figure 3).
