Figure Lengend Snippet: The applied workflow during an online-adaptive treatment session: A planning computed tomography (CT) scan is acquired prior to treatment and serves as the reference for initial planning ( 1 ). A daily cone beam CT (CBCT 1) is obtained at the beginning of each treatment session ( 2 ). Daily anatomical variations are delineated on this image and used for online-adaptive treatment planning. An independent verification software (Mobius 3D v4, Varian Medical Systems, Palo Alto, CA, USA) is employed to validate the adaptive plans prior to treatment ( 3 ). A second CBCT 2 ( 4 ) is used to account for intra-fraction motion during the planning period, and the online-adaptive treatment fraction is delivered immediately afterward ( 5 ).
