Feasibility of MV CBCT-based treatment planning for urgent radiation therapy: dosimetric accuracy of MV CBCT-based dose calculations. [PDF]

open access: yes, 2015
Unlike scheduled radiotherapy treatments, treatment planning time and resources are limited for emergency treatments. Consequently, plans are often simple 2D image-based treatments that lag behind technical capabilities available for nonurgent ...

Checklist and quality assurance tools for integration of two radiation oncology information systems (ROISs)

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Merging two radiation oncology information systems (ROISs) is often necessary due to system changes or hospital integrations. ROIS integration is a high‐risk procedure, that requires clear procedural guidelines and comprehensive QA methods to ensure safe practice.

Reducing low‐dose exposure in helical TomoTherapy for locally advanced left‐sided breast cancer with a deformable image registration–based dose‐mimicking workflow

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Helical TomoTherapy provides highly conformal dose distributions for breast irradiation but is limited by extensive low‐dose spillage (“low‐dose bath”), contributing to increased integral dose and potential long‐term toxicities. Complete blocks can suppress low‐dose spread, but at the cost of prolonged treatment times on legacy ...

Evaluation and implementation of an independent Kilovoltage X‐ray‐based imaging platform for carbon ion radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Background Image‐guided particle therapy (IGPT) has significantly advanced in recent years, particularly in the context of proton therapy. However, imaging solutions for carbon‐ion radiotherapy (C‐ion RT) remain limited. Purpose This study introduces sliding‐gantry cone‐beam computed tomography (CBCT) and dual‐panel digital radiography (DR ...

Quantifying the impact of tumor size and motion on 4DCT‐4DCBCT image registration accuracy using machine learning and statistical analysis

open access: yesJournal of Applied Clinical Medical Physics, Volume 27, Issue 2, February 2026.
Abstract Purpose This study systematically quantifies the effects of five variables—respiratory cycle, tumor size, and motion amplitudes in the superior‐inferior (SI), anterior‐posterior (AP), and left‐right (LR) directions—on the registration accuracy between four‐dimensional computed tomography (4D CT) and four‐dimensional cone‐beam CT (4D CBCT ...
