Figure 1. Dose profile over the target volumes in a DPBC plan, showing the steep gradients of the prescribed dose (52.8 Gy to PTV3, 60 Gy to PTV2, 69.7 Gy to PTV1, 73.1 Gy to PTV-solid and 79.7 Gy to PTV-PET) and the smoother gradients of the achieved plan dose.

Table I. Prescription doses, mean doses and doses covering 95% of the target volume.
Table II. Comparison of the dose-painting plans of different prescription approaches by means of four different scalar measures.
Figure 2. The QVH of a suboptimal plan (solid line), shown in relation to the ‘normal zone’ of the QVH tool. The plan was re-optimized and could be improved (dotted line).
