Empirical distribution functions of the DeltaDmax values in the central bronchial wall from adaptive plans calculated an CBCT1 and CBCT2. a, DeltaDmax values from 5 patients with 48 fractions treated with adaptive plans plans optimized according to method 1 (red step function). The red step function shows the DeltaDmax values from the 5 patients with 43 fractions and adaptive plans optimized according to method 2
