Tooth Retrospective Dosimetry Using Electron Paramagnetic Resonance: Influence of Irradiated Dental Composites. [PDF]

PLoS ONE, 2015
In the aftermath of a major radiological accident, the medical management of overexposed individuals will rely on the determination of the dose of ionizing radiations absorbed by the victims.

Quantification of 10B and 11B in Biological Samples in Translational Science and Clinical Applications for Boron Neutron Capture Therapy (BNCT)

Medicinal Research Reviews, Volume 46, Issue 5, Page 1362-1389, September 2026.
ABSTRACT Boron neutron capture therapy (BNCT) is a targeted radiotherapy that exploits the selective accumulation of the 10B isotope within tumors, followed by irradiation with low‐energy neutrons to induce high linear energy transfer particles with short path lengths, resulting in localized tumor cell destruction while sparing surrounding healthy ...

Patient Dimensions From a Single CT Image Provide a Clinically Practical and Accurate Method for Dose Estimation in Canine Abdominal CT Imaging

Veterinary Radiology &Ultrasound, Volume 67, Issue 5, September 2026.
ABSTRACT Size‐specific dose estimate (SSDE) uses linear dimensions measured on a computed tomographic (CT) image to scale the scanner‐reported volumetric computed tomography dose index (CTDIvol) and thereby estimate dose. The objectives of this retrospective observational study were to evaluate whether the American Association of Physicists in Medicine

Probabilistic quality assurance of biopsy DVH thresholds in HDR prostate brachytherapy under localization uncertainty

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background MR‐US guided biopsies support biologic correlation in HDR prostate brachytherapy, but steep dose gradients and millimeter‐scale localization uncertainty limit the validity of nominal biopsy doses. Purpose To assess how localization uncertainty affects the robustness of biopsy DVH dose thresholds in HDR prostate brachytherapy and to ...

End‐to‐end deep learning pipeline for automated IMRT planning in lymphoma: Feasibility and limitations

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Intensity‐modulated radiation therapy (IMRT) is widely used for lymphoma because a multileaf collimator (MLC) can sculpt dose around irregular targets. Planning, however, is time‐consuming and difficult to standardize. Fluence map prediction (FMP) using deep learning (DL) could potentially be used to automate planning, but it has ...

Retrospective methods to estimate radiation dose at the site of breast cancer development after Hodgkin lymphoma radiotherapy

Clinical and Translational Radiation Oncology, 2017
Background: An increased risk of breast cancer following radiotherapy for Hodgkin lymphoma (HL) has now been robustly established. In order to estimate the dose–response relationship more accurately, and to aid clinical decision making, a retrospective

Commissioning and clinical positioning assessment of a novel surface‐guided radiation therapy (SGRT) system at a C‐Arm linear accelerator

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Surface‐guided radiation therapy (SGRT) has been increasingly adopted in modern radiotherapy, enabling radiation‐dose‐free, marker‐free patient positioning with high accuracy. A novel SGRT system, LUNA 3D (LAP, Lüneburg, Germany), featuring a browser‐based interface, GPU‐accelerated surface reconstruction, high frame rates, large ...

Dosimetric correlation between exit dose maps and anatomical changes in head and neck cancer treatment on Halcyon‐E: A gamma analysis approach

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Head and neck cancer (HNC) has a high incidence in Brazil. Although Image‐Guided Radiation Therapy (IGRT) improves treatment precision, anatomical changes during the treatment course may compromise dose distribution and require replanning.

Assessment of dose distribution in pancreatic SABR in the presence of a metallic biliary stent using Monte Carlo modeling

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Stereotactic ablative radiotherapy (SABR) with dose escalation is increasingly used for pancreatic cancer; however, the dosimetric impact of metallic biliary stents remains poorly characterized. Self‐expanding metal stents (SEMS), commonly placed for obstructive jaundice, contain high‐density nitinol that produces computed ...

Treatment plan dosimetric impact after catheter stretch during multi-catheter interstitial breast brachytherapy

Journal of Contemporary Brachytherapy, 2017
Purpose: Nylon 6/6 interstitial brachytherapy catheters may stretch when exposed to moisture, mechanical tension, and body temperature. The purpose of this study is to evaluate the magnitude of catheter stretch during a course of multi-catheter ...
