Figures & data

Table 1. Baseline patient characteristics.

Figure 1. IMPT and VMAT re-planning frequencies for treatment-trajectories with and without re-planning. Decisions to re-plan were based on the weekly repeated 4DCTs only, i.e., without dose accumulation. Whole-course ICTV coverage was evaluated with dose accumulation on the average planning 4DCT.
