Modeling daily changes in organ-at-risk anatomy in a cohort of pancreatic cancer patients.
CONCLUSIONS: Anatomical variations influence the delivered doses to healthy organs during SBRT. A motion model was successfully built and explored to extract the larger directions of movement of the gastrointestinal organs. Day-to-day motion modeling can potentially be used to account for geometrical uncertainties in future plan optimization and in online adaptive strategies.
