| Popis: | Background To test the hypothesis that the therapeutic ratio of intensity-modulated photon therapy using helical tomotherapy (HT) for retreatment of head and neck carcinomas can be improved by robust intensity-modulated proton therapy (IMPT). Methods Comparative dose planning with robust IMPT was performed for 7 patients retreated with HT. Results On average, HT yielded dose gradients steeper in a distance ≤ 7.5 mm outside the target (p |
