Fig. 4. Local gamma passing rates with various passing criteria calculated from the PTW–VeriSoft® dosimeter measurements are shown for (a) the 80 and 140 kVp plans and (b) the 120 and 140 kVp plans. Global gamma passing rates with various passing criteria calculated from the PTW–VeriSoft® dosimeter measurements are shown for (c) the 80 and 140 kVp plans and (d) the 120 s and 140 kVp plans. The dosimetric effects for the four treatment sites (brain metastases plans, head and neck cancer plans, lung cancer plans, and prostate cancer plans) were analyzed. The error bars above the histogram indicate the standard deviation.
