Conclusion:

From the results for simple rectangular fields, we conclude that a homogeneous rather than heterogeneous phantom image appears to be more suited for ArcCHECK verification with MC. For these simple fields, no performance benefit from either MC or CC is found. However, MC might offer performance benefits over CC for more complex treatment plans. Results from clinical treatment plans suggest that our MC model performs comparable to our CC model for 6 MV. Notably, for 6 MV FFF, MC resulted in consistently better ArcCHECK results (10% to 58% lower mean gamma) as compared to CC.
