Figure 7. Comparison of extremely inhomogeneous versus rather homogeneous doses of gross tumor volume of 5-40 mm.

Figure 7

The images show the BWPs along with the results of Wilcoxon signed-rank test (A-D); the spillage volume of the PD outside the GTV (A); the GI (B); the spillage volume of 50% of the PD outside the GTV (C); and the D98% (%) of the GTV + 2 mm object, relative to 100% of the PD (D).

(A-D) The EIH plans in this comparison include 86.4%, 75.1% and 68.6% IDS-covered plans for 5-, 8- and 9-mm GTV, respectively, in addition to the EIH plans for GTV of ≥10 mm. (A, B, D) The x-indications beyond the whiskers show outliers >1.5 times the IQR.

EIH, extremely inhomogeneous; RH, rather homogeneous; GTV, gross tumor volume; BWP, box-and-whisker plot; PD, prescribed dose; IDS, isodose surface; IQR, interquartile range
