Establishing Traceability for Radiotherapy Dose Calibration In Ukraine

Amid ongoing war, Ukraine continues to maintain and modernize radiation therapy (RT) services. Between 2023 and 2025, 24 linacs were installed to replace aging, non-rechargeable cobalt units. While linacs offer clinical advantages, they require stringent dosi...

Retrospective Estimation of Linear Energy Transfer Distributions within Pediatric Patients Treated with Passive Scattering Proton Therapy

The NCI Pediatric Proton and Photon Therapy Comparison Cohort aims to compare the risk of second malignancies in patients treated with proton versus photon radiotherapy. Using Monte Carlo (MC) simulations, normal tissue dose estimates were retrospectively cal...

Organ and Detriment-Weighted Dose Estimates within a Large Study on Fluoroscopically Guided Interventional Procedures Performed In the United States

A multi-institution study is underway to characterize the organ doses received by adult patients undergoing ten common types of fluoroscopically guided interventional (FGI) procedures in the United States. Unlike diagnostic procedures, FGI are not standardize...

Pediatric Cardiac Substructure Dose Coefficients for Chest and Abdomen–Pelvis CT Using a Size-Dependent Whole-Body Phantom Library

Pediatric dose from CT remains a concern, and recent evidence from radiotherapy has increased interest in dose to specific cardiac substructures (e.g., the left anterior descending coronary artery). Pediatric whole-body phantoms that contain detailed cardiac...
