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 ...

A review on radiochromic film dosimetry in radiation therapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract Radiochromic films (RCFs) are ubiquitous in radiation oncology clinical and research settings to measure the radiation dose over a two‐dimensional (2D) area due to their high spatial resolution, water‐equivalency, and relative ease‐of‐use. Upon irradiation, the constituent monomers of the active layer of RCFs undergo polymerization, leading to
