STAT-ART: The Promise and Practice of a Rapid Palliative Single Session of MR-Guided Online Adaptive Radiotherapy (ART)

Frontiers in Oncology, 2019
This work describes a novel application of MR-guided online adaptive radiotherapy (MRgoART) in the management of patients whom urgent palliative care is indicated using statum-adaptive radiotherapy (STAT-ART). The implementation of STAT-ART, as performed

Dual‐scan conformal cone‐beam CT for targeted image‐quality improvement using dynamic collimation

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is routinely used for image guidance in radiation therapy, but conventional full‐field CBCT acquisition may expose anatomically irrelevant regions and generate substantial scatter, which degrades soft‐tissue contrast and limits the accuracy of target localization and adaptive radiotherapy ...

Multi-institutional experience treating patients with cardiac devices on a 1.5 Tesla magnetic resonance-linear accelerator and workflow development for thoracic treatments

Physics and Imaging in Radiation Oncology
Background and purpose: Patients with cardiac implantable electronic devices (CIED patients) are often ineligible for online magnetic resonance-guided radiotherapy (MRgRT), most likely due to the absence of established guidelines.

Evaluation of an Early Regression Index (ERI_TCP) as Predictor of Pathological Complete Response in Cervical Cancer: A Pilot-Study

Applied Sciences, 2020
Background: Recent studies have highlighted the potentialities of a radiobiological parameter, the early regression index (ERITCP), in the treatment response prediction for rectal cancer patients treated with chemoradiotherapy followed by surgery.

Synthetic CT‐enabled weekly adaptive radiotherapy for nasopharyngeal carcinoma: Optimizing plan adaptation triggers through volumetric–dosimetric monitoring

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background and purpose Anatomical changes during radiotherapy for nasopharyngeal carcinoma (NPC) frequently compromise target volume coverage while escalating dose delivery to organs at risk (OARs). In adaptive radiotherapy (ART), optimizing workflow efficiency to minimize clinical workload while maximizing patient benefit remains a ...

Longitudinal CT number characterization of a novel upright CT for proton therapy planning

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background: The combination of upright CT and patient positioner for particle therapy presents potential for high precision image‐guided radiation therapy and online adaptive radiation therapy, where reliable CT performance is essential. Purpose: To evaluate the longitudinal stability of upright CT for proton radiation therapy, benchmark ...

The illusory correlation between geometrical similarity and physician satisfaction in heart auto‐segmentation revealed by a physician‐blind test

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Auto‐segmentation tools are essential in adaptive radiation therapy (ART). While evaluation typically relies on geometric metrics like Dice similarity coefficient (DSC), high scores do not always translate to clinical acceptability.

Quantitative assessment of CBCT image quality metrics and their translation to clinical Art workflow performance in breast cancer patients

Journal of Applied Clinical Medical Physics, Volume 27, Issue 6, June 2026.
Abstract Background Online adaptive radiotherapy (ART) relies on cone‐beam computed tomography (CBCT) imaging for daily treatment adaptation, but CBCT's physical limitations can compromise contour delineation and dose calculation accuracy. The relationship between image quality metrics and clinical ART workflow accuracy remains unclear.
