Figure 3

Cumulative histograms of (a) observed mean γ values and (b) percentages of rejected pixels when comparing measured and predicted PDIs for combined fractions. For in-vivo measured PDIs, results are shown for images acquired in the first fraction and for combinations of the first 2, 3, 4, and 5 fractions. All in-vivo PDI predictions were based on a CBCT. CBCT and in-vivo PDIs were always acquired in the same fraction.
