Dosimetric study for spine stereotactic body radiation therapy: magnetic resonance guided linear accelerator versus volumetric modulated arc therapy

Radiology and Oncology, 2019
Stereotactic body radiation therapy (SBRT) given in 1-5 fractions is an effective treatment for vertebral metastases. Real-time magnetic resonance-guided radiotherapy (MRgRT) improves soft tissue contrast, which translates into accurate delivery of spine

Initial follow‐up of mechanical QC tests for RapidArc Dynamic (RAD)

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background RapidArc Dynamic (RAD) is a new solution for delivery of radiotherapy introduced by Varian. RAD blends Volumetric Modulated Arc Therapy (VMAT) and Intensity‐Modulated Radiation Therapy (IMRT) by pausing gantry rotation at predefined positions and adds a degree of freedom: a dynamic collimator.

Patient‐specific quality assurance for extremely small field sizes using 3D in vivo dosimetry in fractionated stereotactic radiosurgery for brain metastases

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Fractionated stereotactic radiosurgery (fSRS) using LINAC‐based volumetric‐modulated arc therapy (VMAT) has become widely adopted and achieved favorable outcomes. However, this technique involves extremely small field sizes, making pre‐treatment quality assurance (QA) with high‐resolution detectors essential.

Machine learning‐based integration of radiomics and dosiomics for early prediction of radiation‐induced temporal lobe injury in nasopharyngeal carcinoma: A multicenter study

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose This study developed and validated a multimodal machine learning model integrating clinical, radiomics, and dosiomics characteristics to predict radiation‐induced temporal lobe injury (RTLI) in nasopharyngeal carcinoma patients. Methods This study utilized dual‐center retrospective cohorts comprising 213 patients. From pre‐treatment 3D

Determining optimal transit dosimetry gamma parameter values for the detection of failure modes using receiver operating curve analysis

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Purpose To determine the gamma criteria that maximize the sensitivity and specificity of the transit dosimetry software PerFRACTION (Sun Nuclear Corporation) under five possible failure modes in external beam radiotherapy. Methods We simulated five failure modes that potentially introduce large changes in the absorbed dose distribution: (1 ...

Dosimetric Comparison Using an Intraoral Stent during Volumetric-modulated Arc Therapy in a Patient with Carcinoma of the Tongue

Journal of Radiation and Cancer Research
A 47-year-old man diagnosed with carcinoma of the tongue and postsurgery was planned for adjuvant radiotherapy. He was simulated for radiotherapy with or without an acrylic intraoral stent (IOS). Two different radiotherapy treatment plans with volumetric-
