  In this manuscript, we investigated the accuracy of the entire chain of phase
space files generated by the TrueBeam VirtuaLinac system in clinical treatment
plans. Good agreement was obtained between the MC simulation and the clinical
golden data for both flattened and FFF beams. The relative magnitude of
agreement between MC and golden beam data presented in this research may assist
a physicist in terms of the percent dose deviation that one may expect when
using MC data for verification purposes.
