Figure 4: DVH-based curves of the rectal wall for cases that did not pass the criterion of V78 Gy<1% for any of the four KBP models. The KBPORIG, KBPC-DVH, and KBPC-REGmodels had two cases (a and b), four cases (a and c-e), and three cases (c, f and g), respectively, that did not meet the V78 Gy<1% criterion. The DVH curves for KBPORIG, KBPC-DVH, and KBPC-REGshow a long tail close to the maximum dose in some cases, whereas that for KBPC-ALLhad no tail in any case.
