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

Journal 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.

Active bone marrow dose reconstruction in a large‐scale cohort study of cancer patients treated with photon radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background Previous studies have investigated the dose‐response relationship between external beam radiotherapy (EBRT) and leukemia by reconstructing the mean active bone marrow (ABM) dose as part of the exposure assessment. However, no prior study has leveraged electronic medical records (EMR) to reconstruct ABM dose and dose‐volume in an ...

An automated method to establish patient specific asymmetric intrafraction motion monitoring tolerances for prostate radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose Intrafraction motion management is recognized as a critical component of radiotherapy. While clinical trials often recommend its use, they rarely define motion management tolerances. Consequently, institutions set tolerance levels independently, often without considering patient specific anatomy, dose distributions or direction of ...

OVH‐guided planning for superior heart and lung sparing in breast cancer radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background and purpose Manual planning in breast cancer radiotherapy is often time‐consuming and operator‐dependent, leading to inconsistencies in plan quality. This study validated an automated workflow using overlap volume histograms (OVH) to predict patient‐specific dose–volume histogram (DVH) constraints, aiming to enhance cardiopulmonary ...

Dysphagia optimized knowledge‐based planning for head and neck cancer

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose Swallowing dysfunction after radiotherapy (RT) is often linked to pharyngeal mucosal damage. This study aimed to develop a dysphagia‐optimized knowledge‐based planning (DO‐KBP) model by incorporating individual pharyngeal constrictors (DO‐KBP) into an existing model, which was based on a conventional approach of including pharynx as a ...

Impact of CT calibration curves on radiotherapy planning using diagnostic CT scans and a planning CT supporting DirectDensity reconstruction

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Purpose DirectDensity enables tube voltage‐independent, density‐calibrated computed tomography (CT) images for treatment planning and is therefore increasingly used in radiotherapy facilities. In accelerated emergency workflows, diagnostic CT (dCT) data are often acquired without DirectDensity.
