Figure 1: Population mean difference in dosimetric plan parameters of IMPT&TPB and IMPT treatment plans for nasopharyngeal ca. patient (left) and oropharyngeal CA. patients (right). Statistical significance is denoted by asterisks (p>0.05) For both tumour localisations, the optimiser focused TPB contributions in regions between the target and the highest priority OARs (especially the parotid glands in the applied wish-list), where they can enhance lateral dose fall-off. Figure 2 shows a typical example of an oropharynx case.
