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

Journal 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

A novel system for micron‐scale analysis of energy deposition and response to low‐dose radiation

Medical Physics, Volume 53, Issue 3, March 2026.
Abstract Background Micrometer‐scale evaluation of energy deposition is important for radiation protection and therapy as well as for advancing knowledge of responses to radiation in materials and biological systems. Due to the stochastic nature of radiation interactions, there is significant variation in energy deposition in micrometer‐sized targets ...
