Linear transformation QVHs as a function of beamlet size and fixed pitch for the complex HNSCC patient. QVH of the PTV for decreasing jaw width and fixed pitch of 0.86 applied to $P_{\text{max}}^{n=1}$ cases (a) and $P_{\text{int}}^{n=1}$ cases (b). Note that dose plans conform more closely to the prescription and converge as the jaw width approaches longitudinal dimension of the PET voxels (0.391 cm).
