(a) The measured dose distribution and gamma analysis that compares with the (b) SC and (c) MC calculated dose distributions in flat phantom for one of the patient treatment fields. The percentage of points passed was calculated for γ <1 with 2% tolerance and 2 mm DTA. The agreement of MC results is better than SC. Note that the color bar in (a) represents the measured dose in cGy, whereas the color bar in (b) and (c) shows the range of γ values.
