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...

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...
