Quantifying stent‐induced dose perturbations in intravascular brachytherapy using 3D‐ printed phantoms and film dosimetry

Journal of Applied Clinical Medical Physics, Volume 27, Issue 1, January 2026.
Abstract Background Coronary artery disease (CAD), the leading cause of death worldwide, is the narrowing of coronary arteries due to atherosclerotic plaque buildup. A common treatment for CAD is percutaneous coronary intervention (PCI), often involving stent placement. However, a common complication or in‐stent restenosis (ISR) can occur in 10%–20% of

Patient radiation dosimetry for fluoroscopically guided interventions – a review of the history and limitations

Medical Physics, Volume 53, Issue 1, January 2026.
Abstract Fluoroscopically guided interventions (FGIs) play a critical role in modern medicine, though they potentially deliver high radiation doses that require accurate and patient‐specific dosimetry for risk assessment and patient management. This review provides a historical overview of radiation dosimetry in fluoroscopy, tracing the evolution from ...

A review on radiochromic film dosimetry in radiation therapy

Journal of Applied Clinical Medical Physics, Volume 26, Issue 12, December 2025.
Abstract Radiochromic films (RCFs) are ubiquitous in radiation oncology clinical and research settings to measure the radiation dose over a two‐dimensional (2D) area due to their high spatial resolution, water‐equivalency, and relative ease‐of‐use. Upon irradiation, the constituent monomers of the active layer of RCFs undergo polymerization, leading to
