Session Item

Online adaptive radiotherapy treatment allows for adapting the treatment plan to the anatomical changes between the reference CT scan it was based on and the actual treatment session(s). The first online adaptive treatments were MR-Linac based and for limited number of patients, treatment sites and/or fractions. Conebeam CT based options are currently also commercially available and patient, treatment sites and/or fraction numbers are increasing.

Online adaptive radiotherapy started out as a resource heavy option with long time slots and a multi-disciplinary team at the treatment machine.

This presentation will be focused on RTT-only online adaptive radiotherapy, and gives an overview of (1) local online adaptive radiotherapy, (2) workflow and responsibilities, (3) training to build competence and confidence for RTT-only online adaptive radiotherapy and (4) overview of literature.
