Fig. 1 Lesion 9 shown for the 3D and 4D scan (best bin) with the same window/level settings. Radiotherapy and Oncology 2012 102, 377-382DOI: (10.1016/j.radonc.2011.12.015) Copyright © 2012 Elsevier Ireland Ltd Terms and Conditions
Fig. 2 The PD between the pre-RT 3D and 4D scans. The lesions on the plot are also classified according to their SAR, with the dotted and dashed lines showing the average PDpre for SARs greater and less than 8, respectively.

Fig. 3 (A) A bar plot showing the PC3D and PC4D for each lesion and (B) the DPC against the range of tumor motion (R). Also shown is the lesions’ size-to-amplitude (SAR). The dotted and dashed lines show the average DPC for SARs greater and less than 8, respectively.
