Purpose: Phase‐space files for Monte Carlo simulation of the Varian TrueBeam beams have
been made available by Varian. The aim of this study is to evaluate the accuracy of the …

Abstract Purpose Through the Monte Carlo (MC) simulation of 6 and 10 MV flattening-filter-
free (FFF) beams from Varian TrueBeam accelerator, this study aims to find the best incident …

Dosimetry protocols for external beam radiotherapy currently in use, such as the IAEA TRS-
398 and AAPM TG-51, were written for conventional linear accelerators. In these …

Purpose: With the introduction of flattening filter free (FFF) linear accelerators to radiation
oncology, new analytical source models for a FFF beam applicable to current treatment …

This study investigates the superficial dose from FFF beams in comparison with the
conventional flattened ones using a Monte Carlo (MC) method. Published phase-space files …

Purpose: A linac delivering intensity‐modulated radiotherapy (IMRT) can benefit from a
flattening filter free (FFF) design which offers higher dose rates and reduced accelerator …

Purpose: To establish the clinical acceptability of universal Monte Carlo phase–space data
for the 10XFFF (flattening filter free) photon beam on the Varian TrueBeam Linac, including …

PURPOSE: To investigate dosimetric characteristics of a new linear accelerator designed to
deliver flattened, as well as flattening filter-free (FFF), beams. To evaluate the accuracy of …

Purpose: To compare dosimetric characteristics of 6 MV photon fields originating from a
linear accelerator operating with (FF) and without (FFF) a flattening‐filter. The main objective …

Monte Carlo simulation of linear accelerators (linacs) depends on the accurate geometrical
description of the linac head. The geometry of the Varian TrueBeam linac is not available to …
