Plan deliverability robustness was explored by identifying and gating motion-sensitive control point sequences in single-target cranial VMAT plans. A dose-informed, control-point-specific motion tolerance was tested for its performance in mitigating coverage...

Planners must often choose how to cluster multiple SRS/SRT targets without reliable a priori dosimetric prediction, making exhaustive plan-and-optimize testing impractical in complex cases. A previously developed target-clustering metric (M) was designed as a...

This study investigates the performance of silicon semiconductor detectors in combination with a plastic scintillation detector (PSD) for measuring photon beam doses under clinically relevant conditions.

During the implementation of the pilot of the Canadian Association of Radiologists’ (CAR) Lung cancer screening program, our healthcare system had to adapt our existing practices and protocols. Our physicists decided to investigate the effect these changes ha...

To assess the high-dose performance of organic thin-film transistors (OTFTs) for radiotherapy applications and to identify material-level effects impacting detector response.

Present interim dosimetry analysis from a prospective, multi-center study (NCT05953337) comparing the mean absorbed dose (Dmean) derived from nuclear medicine (NM) and CT imaging of liver cancer patients undergoing yttrium-90-radioembolization (90Y-RE) with r...

This session is jointly organized by the Working Group on Radiation Dosimetry and Task Group 359 on FLASH (ultra-high dose rate) radiation dosimetry. The session will begin with an educational review of currently available radiation dosimeters used for both c...

Automation has become integral to modern radiation oncology—including image registration, contouring, planning, adaptive workflows, and quality assurance (QA). While these systems improve efficiency, they also introduce new vulnerabilities when automation fai...
