Cumulative dose–volume histograms (DVHs) for the clinical target volume. (a) The DVHs for patient 5 show large discrepancies between the deformation organ sets. (b) The DVHs for patient 7 are more typical of the discrepancies between organ sets for the entire group of patients. $\mathrm{L}\mathrm{H}\mathrm{C}\mathrm{E}=\mathrm{f}\mathrm{o}\mathrm{u}\mathrm{r}-\mathrm{d}\mathrm{i}\mathrm{m}\mathrm{e}\mathrm{n}\mathrm{s}\mathrm{i}\mathrm{o}\mathrm{n}\mathrm{a}\mathrm{l}\hspace{0.17em}(4\mathrm{D})$ dose calculation driven by deformations of lung, heart, cord, external contour; $\mathrm{L}\mathrm{H}\mathrm{C}=4\mathrm{D}$ dose calculation driven by deformations of lung, heart, cord; $\mathrm{L}\mathrm{H}=4\mathrm{D}$ dose calculation driven by deformations of lung, heart; $\mathrm{L}\mathrm{E}=4\mathrm{D}$ dose calculation driven by deformations of lung, external contour; $\mathrm{L}\mathrm{C}=4\mathrm{D}$ dose calculation driven by deformations of lung, cord; $\mathrm{L}=4\mathrm{D}$ dose calculation driven by deformations of lung.
