Fig. 8From: 4DMRI-based investigation on the interplay effect for pencil beam scanning proton therapy of pancreatic cancer patientsEstimation of the statistical evolution of the interplay effect based on a single 4DMRI (red) compared to 5/3 4DMRI scans for P2/P8 (blue), respectively, for 30 simulated treatments. In the multi-4DMRI scenarios, the underlying motion pattern was randomly sampled for each fraction. The solid lines represent the respective mean d5/d95 valuesBack to article page
