Fig. 3From: Adaptive planning based on single beam optimization in passive scattering carbon ion radiotherapy for patients with pancreatic cancerThe mean dose difference of all fractions in CTV V95 at each beam angle. CTV1 doses were based on the first nine fractions. These differences are in respect to the original plan. CTV, clinical target volume; ns, P > 0.05. A significant difference was obtained between methods without ns (P < 0.05)Back to article page
