Pre-treatment radiotherapy dose verification using Monte Carlo doselet modulation in a spherical phantom
Reid W Townson, Sergei Zavgorodni
Due to the increasing complexity of radiotherapy delivery, accurate dose verification has become an essential part of the clinical treatment process. The purpose of this work was t…
Monitor backscatter factors for the Varian 21EX and TrueBeam linear accelerators: measurements and Monte Carlo modeling
Sergei Zavgorodni, Eyad Alhakeem, Reid Townson
Purpose/Objective: Backscattered radiation (BSR) into linac monitor chamber has to be accounted for in radiotherapy dose calculations. In Monte Carlo (MC) calculations, the BSR can…
Monte Carlo investigation into feasibility and dosimetry of flat Flattening Filter Free beams
Sergei Zavgorodni
Flattening filter free (FFF) beams due to their non-uniformity, are sub-optimal for larger field sizes. The purpose of this study was to investigate the incident electron beam dist…
GPU-based Monte Carlo radiotherapy dose calculation using phase-space sources
Reid Townson, Xun Jia, Zhen Tian +3
A novel phase-space source implementation has been designed for GPU-based Monte Carlo dose calculation engines. Due to the parallelized nature of GPU hardware, it is essential to s…
