CBCT-based online adaptive radiotherapy (CBCT-oART) enables daily plan adaptation but is sensitive to intra-fraction motion during extended adaptive workflows. This study evaluates breath-hold (BH) motion stability and workflow impact using an in-bore surface...

Lung cancer cases frequently involve multiple lesions, and treatment with a single isocenter can introduce geometric uncertainties, particularly due to inter-fraction motion. Online adaptive radiotherapy (ART) offers a strategy to mitigate these effects. This...
