Figure 2

Cumulative histograms of (a) observed mean γ values and (b) percentages of rejected pixels when comparing measured and predicted PDIs. Prediction of in-vivo PDIs for the 1413 measured images was based on either CBCT or pCT. Results for the corresponding 313 pretreatment measurements were included as well. (c) and (d) show cumulative histograms of differences between CBCT- and pCT-based prediction.
