Static IMRT and VMAT planning on 6 MV Flattened and Flattening-Filter-Free Beams of a TrueBeam VirtuaLinac System

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.
