Quantifying setup uncertainty between computed tomography guidance and magnetic resonance guidance in intramuscular metastases radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 4, April 2026.
Abstract Background and purpose MR‐Linac (MRL) is well‐suited for treatment of oligometastatic disease (OMD) in muscle due to its superior soft tissue contrast. The purpose of this study was to assess dosimetric differences and quantify margins when CT‐guidance (CTgRT) is used for OMD treatment compared to MR‐guidance (MRgRT) on the MRL.

Comparison of gantry-less magnetic resonance guided proton therapy with photon therapy for hepatocellular carcinoma patients

Physics and Imaging in Radiation Oncology
Background and purpose: With magnetic resonance imaging (MRI), soft-tissue tumors such as hepatocellular carcinoma (HCC) are visualised. MR guided proton therapy (MRgPT) may combine the advantages of proton therapy with soft-tissue image-guidance ...

Safety and Tolerability of Online Adaptive High-Field Magnetic Resonance-Guided Radiotherapy [PDF]

Importance: In 2018, the first online adaptive magnetic resonance (MR)-guided radiotherapy (MRgRT) system using a 1.5-T MR-equipped linear accelerator (1.5-T MR-Linac) was clinically introduced.

Feasibility and Tumor Dynamics of Daily MRI‐Guided Online Adaptive Radiotherapy for Brain Glioma

CNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
The apparent tumor dynamics were observed during chemoRT in patients with brain glioma. MRIgOART not only corrected daily anatomical variations but also enabled real‐time assessment of treatment response, thereby facilitating dynamic optimization of concomitant therapy protocols.

MR-Linac Dosimetry: Current Approaches and Challenges

Journal of Physics: Conference Series, 2023
Abstract The use of MR-integrated linacs (MR-linac) in clinical radiation oncology applications are becoming more prevalent. However, given the novel and radically different designs of these systems from conventional linacs, current radiation dosimetry protocols for high energy photons are no longer appropriate for use in modern MR-linac

A simulation study of a novel spiral volumetric modulated arc therapy for enhanced dose delivery efficiency and quality in radiotherapy

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background Conventional volumetric modulated arc therapy (VMAT) is limited by its longitudinal field size for large targets, often requiring multiple isocenters, while Helical Tomotherapy (HT) offers superior longitudinal conformity but suffers from prolonged treatment times due to its narrow fan beam.

Accumulated dose on daily iCBCT for rectal cancer: Effects of inter‐fraction bowel cavity motion volume

Journal of Applied Clinical Medical Physics, Volume 27, Issue 3, March 2026.
Abstract Background To assess how inter‐fraction bowel cavity (BC) motion volume influences accumulated dose in rectal cancer radiotherapy and to translate these effects into a clinically interpretable risk construct for acute bowel toxicity. Methods This retrospective cohort included 28 consecutive rectal cancer patients treated with 50 Gy in 25 ...
