Application of an updated severity‐based FMEA approach to Radiation Therapy QA: A multi‐institutional exercise

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background External beam radiation therapy (RT) involves many complex steps to safely and reliably treat patients. The radiation oncology community has adopted process maps and failure modes and effects analysis (FMEA) to analyze risk using the TG‑100 methodology, but the traditional TG‑100–endorsed risk priority number (RPN) has recognized ...

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.

A geometry‐based scaling model for stereotactic treatment volume definition in stereotactic centralized ablative radiation therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Stereotactic Centralized Ablative Radiation Therapy (SCART) is a spatially fractionated radiotherapy strategy designed for large or bulky tumors by delivering an intensified ablative dose to a centrally located subvolume while allowing controlled dose reduction toward the tumor periphery.

Dosimetric and clinical validation of a high‐density bolus for superficial skin tumors treated with radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Accurate dose deposition in superficial radiotherapy remains challenging due to the inherent skin‐sparing effect of megavoltage photon beams and difficulties in ensuring bolus conformity. Purpose This study aims to comprehensively evaluate the dosimetric characteristics of the room‐temperature‐malleable high‐density bolus, to ...

Performance evaluation of a new type of commercial silicon detectors for photon beam dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Modern radiotherapy relies on advanced treatment techniques that utilize a large number of small fields, for which maintaining dosimetric accuracy is often challenging. Most vendors have introduced microdetectors suitable for small field dosimetry. Sun Nuclear has developed two silicon diodes with a sensitive volume of 0.35 mm3 that
