Accelerated partial breast irradiation (APBI) combined with online adaptive radiotherapy (OART) offers precise treatment of early-stage breast cancer, but inter-observer variability (IOV) in target delineation must be accounted for to maintain treatment quali...

Radiotherapy treatment planning is a resource-intensive process characterized by multiple manual steps that can contribute to treatment delays and inter-observer variability. The Radiation Planning Assistant (RPA) is a web-based platform designed to deliver a...

Automated radiotherapy treatment planning pipelines can reduce planning time and improve standardization, but clinical adoption is often limited by the time and specialized automation expertise required to define, configure, and maintain these pipelines. We d...

CT-guided adaptive radiotherapy (CTgART) introduces substantial workflow complexity and resource demands. While clinical experience is expected to improve efficiency, the magnitude and structure of adaptive learning have not been well quantified using objecti...

CT-guided online adaptive radiotherapy(CTgART) introduces substantial per-patient variability in session duration, complicating prospective scheduling. This study evaluates whether system-reported reference plan calculation metrics, specifically reference pla...

Online adaptive radiotherapy (oART) mitigates interfraction motion and enables potential reduction of planning target volume (PTV) margins relative to standard-of-care approaches. This study evaluates the robustness of 2 mm PTV margins in a prospective stereo...

Radiotherapy planning requires frequent interaction with complex clinical software, creating inefficiency and opportunities for error. Current automation pipelines depend on scripting, large datasets, or vendor-specific APIs. Here, we assess whether a one-sho...

Clinical medical software is often deployed through streamed environments such as Citrix, where conventional automation methods fail due to the lack of native operating system controls and application programming interfaces. This work presents a visual-langua...

Radiotherapy plan quality education is limited by case availability, frequent clinical interruptions, and difficulty aligning schedules. These barriers leave residents underprepared to identify and correct suboptimal plans, potentially compromising future out...
