Abstract

Abstract: This study presents estimation of typical kV fluoroscopic imaging doses for image-guided real-time adaptive radiotherapy. For a cohort of 10 lung SABR patients the estimated imaging dose to ipsi-lateral lung with real-time adaptation is 9.9–15.1 cGy, which is less than the extra lung dose from treatment with potentially larger ITV-based PTV approach.
