Monte Carlo simulation of 6 MV flattening filter free photon beam of TrueBeam STx LINAC at Songklanagarind Hospital

In this study, 6 MV photon beam of TrueBeam STx Varian LINAC with Flattening Filter Free (FFF) was simulated using PRIMO code. The depth dose profiles for various jaws open fields and cross beam profiles for various depths inside water phantom were determined using Monte Carlo (MC) simulation techni...
