(a) Differential histogram of target volume sizes in 60 selected patients, with volume sizes corresponding to quartiles 0 to 4 of the population indicated by arrows. Five specific targets with volume sizes corresponding to these quartiles were chosen for the present analysis and displayed in (b–f) in the order of volume size, ranging from the smallest (b, TVA) to the largest (f, TVE). See Table 1 for a detailed description of these five specific targets.
