A geometrical model for the Monte Carlo simulation of the TrueBeam linac [PDF]
, 2015 Monte Carlo (MC) simulation of linacs depends on the accurate geometrical description of the head. The geometry of the Varian TrueBeam (TB) linac is not available to researchers. Instead, the company distributes phase-space files (PSFs) of the flattening-

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.Abstract Background O‐ring linac systems improve radiotherapy efficiency but require rigorous pretreatment verification due to increased delivery uncertainty in IMRT/VMAT. Existing methods face limitations: measurement‐based approaches incur setup errors, while calculation‐based methods (e.g., Monte Carlo) need machine‐specific validation per AAPM TG ...
