Development and validation of a 3D printed phantom for image quality assessment in fluoroscopy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Low‐contrast detectability is a key image‐quality parameter in fluoroscopy, directly influencing diagnostic accuracy and patient safety. Commercial phantoms such as the CDRAD provide reliable assessments but are costly and lack flexibility for routine use. Purpose To develop and validate a low‐cost 3D‐printed phantom for fluoroscopy

Automatic adaptive radiotherapy triggering based on CBCT using deep learning for esophageal cancer underwent volumetric modulated arc therapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Esophageal cancer (EC) is a highly fatal malignancy for which radiotherapy plays a critical role in treatment. However, anatomical changes during radiotherapy can lead to increased doses to surrounding organs at risk (OARs). Adaptive radiotherapy (ART) is a strategy that incorporates patient‐specific anatomic changes into treatment ...

PCA‐based respiratory motion modeling for individualized PTV margin optimization in NSCLC radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Respiratory motion remains a major challenge in radiotherapy for non‐small cell lung cancer (NSCLC), often requiring a balance between target coverage and normal tissue sparing. Introduction This study aimed to develop and validate a clinically implementable, individualized PTV margin strategy by integrating principal component ...

Dosimetric comparison of FF and FFF modes under non‐ideal bolus‐fitting conditions for post‐mastectomy chest wall irradiations

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background In post‐mastectomy radiotherapy, tissue‐equivalent bolus is routinely used to ensure adequate skin dose. However, achieving perfect contact on curved chest walls is challenging, often resulting in non‐uniform air gaps. With the increasing adoption of Flattening Filter‐Free (FFF) beams, it is crucial to understand how their distinct ...
