Clinical validation of a high‐definition mid‐position magnetic resonance imaging approach for lung radiotherapy planning

Medical Physics, Volume 53, Issue 5, May 2026.
Abstract Background Respiratory‐correlated four‐dimensional (4D) magnetic resonance imaging (4D‐MRI) is useful to estimate breathing induced motion for MRI‐guided radiotherapy. Based on 4D‐MR image sets, a three‐dimensional mid‐position (MidP) MRI can be generated using deformable image registration (DIR) for radiotherapy planning. However, the desired

Developing a web‐based dashboard for adaptive radiotherapy workflows

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Purpose Adaptive radiotherapy (ART) is limited by the absence of reliable thresholds to trigger necessary plan adaptation. This work develops and verifies a web‐based, database‐backed dashboard that unifies geometric, dosimetric, and radiobiological metrics to support day‐to‐day ART decisions. Methods Ten retrospectively selected patients were

Measurement validation of treatment planning for a MR‐Linac [PDF]

Journal of Applied Clinical Medical Physics, 2019
AbstractPurposeThe magnetic field can cause a nonnegligible dosimetric effect in an MR‐Linac system. This effect should be accurately accounted for by the beam models in treatment planning systems (TPS). The purpose of the study was to verify the beam model and the entire treatment planning and delivery process for a 1.5 T MR‐Linac based on ...

The role of abdominal compression in the reduction of respiratory motion for cardiac radioablation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background Research on cardiac radioablation (CR) has highlighted the importance of accounting for respiratory‐induced motion during treatment, promoting investigation into methods to reduce its impact. Purpose To investigate the efficacy of abdominal compression (AC) to reduce respiratory‐induced motion for CR patients by quantifying their ...
