PENELOPE/PRIMO-calculated photon and electron spectra from clinical accelerators [PDF]

open access: yes, 2019
Background: The availability of photon and electron spectra in digital form from current accelerators and Monte Carlo (MC) systems is scarce, and one of the packages widely used refers to linacs with a reduced clinical use nowadays.

Soft tissue and water substitutes for megavoltage photon beams: An EGSnrc‐based evaluation [PDF]

open access: yesJournal of Applied Clinical Medical Physics, 2016
In this work, soft‐tissue equivalence of water, polystyrene, PMMA and water equivalence of polystyrene, and PMMA has been assessed for multiple megavoltage photon beams and field sizes. EGSnrc based Monte Carlo (MC) codes, BEAMnrc and DOSXYZnrc are used for the linac head modeling and the phantom dose calculations, respectively. Percentage depth doses (

Commissioning and verification of a 3D Monte Carlo independent calculation software for O‐ring linac systems

open access: yesJournal 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 ...
