Probabilistic quality assurance of biopsy DVH thresholds in HDR prostate brachytherapy under localization uncertainty

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background MR‐US guided biopsies support biologic correlation in HDR prostate brachytherapy, but steep dose gradients and millimeter‐scale localization uncertainty limit the validity of nominal biopsy doses. Purpose To assess how localization uncertainty affects the robustness of biopsy DVH dose thresholds in HDR prostate brachytherapy and to ...

Commissioning and performance evaluations of the electron Monte Carlo algorithm in a new commercial treatment planning system

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Purpose This study provides a comprehensive evaluation of the newly implemented electron Monte Carlo dose calculation algorithm in the commercial treatment planning system, uTPS. It investigates the performance of the algorithm by examining its dosimetric accuracy and calculation speed, which have not been previously reported in the literature.

Accelerated and standardized commissioning of a robotic RadioSurgery system using a hybrid golden beam data model

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background The CyberKnife™ system requires extensive beam data acquisition across multiple collimation systems. The CyberComm™ framework integrates a linac output tuning procedure with a hybrid Golden Beam Data (GBD) model to accelerate and standardize CyberKnife commissioning while maintaining dosimetric accuracy.

Dosimetric correlation between exit dose maps and anatomical changes in head and neck cancer treatment on Halcyon‐E: A gamma analysis approach

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Head and neck cancer (HNC) has a high incidence in Brazil. Although Image‐Guided Radiation Therapy (IGRT) improves treatment precision, anatomical changes during the treatment course may compromise dose distribution and require replanning.

Assessment of dose distribution in pancreatic SABR in the presence of a metallic biliary stent using Monte Carlo modeling

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Stereotactic ablative radiotherapy (SABR) with dose escalation is increasingly used for pancreatic cancer; however, the dosimetric impact of metallic biliary stents remains poorly characterized. Self‐expanding metal stents (SEMS), commonly placed for obstructive jaundice, contain high‐density nitinol that produces computed ...
