Commissioning and clinical implementation of an MLC tracking system: An evaluation of AAPM TG‐264 guidelines

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background Precise radiotherapy relies on accurately targeting tumours while minimising exposure to healthy tissue, yet patient and organ motion complicate treatment delivery. To address intra‐fractional motion, multi‐leaf collimator (MLC) tracking systems have recently been adopted, adapting beam shapes in real‐time.

Commissioning and validation of the Elekta One GPUMCD algorithm for an Elekta VersaHD linear accelerator

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose The purpose of this work was to commission and validate GPUMCD, a GPU‐accelerated Monte Carlo dose calculation engine for c‐arm Elekta linear accelerators (linac). This algorithm was recently released for clinical implementation in the Elekta One Treatment Planning System (v6.2.3, EOP). Methods A GPUMCD beam model was generated for all

Tumor‐Infiltrating Nociceptor Neurons in Ovarian Cancer Treatment Resistance

open access: yesAdvanced Biology, Volume 10, Issue 3, March 2026.
This study shows that high‐grade serous ovarian carcinomas (HGSOC) are significantly more innervated than the other histological subtypes. HGSOC small extracellular vesicles (sEVs) promote neurite outgrowth in vitro. Analysis of pre‐ and post‐treatment HGSOC samples shows that innervation increases post‐chemotherapy.

Li Incorporation Induces Surface Chemical Disorder in Solution‐Processed Cu2ZnSn(S,Se)4

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 5, 4 March 2026.
Lithium incorporation into Cu2ZnSn(S,Se)4 (CZTSSe) thin‐film semiconductors is highly beneficial for solar power conversion efficiencies, although directly visualising its impact on the absorber is difficult. Energy‐filtered photoemission electron microscopy measurements reveal lithium alloying induces surface chemical disorder of CZTSSe, highlighted ...
