Comparison of Ethos template-based planning and AI-based dose prediction: General performance, patient optimality, and limitations

In the field of radiation therapy (RT), adaptive RT (ART) has been a major research topic for many years [1 –3]. Unlike conventional radiation therapy that relies on single computed tomography scans (CT) acquired prior to treatment, ART aims at accounting for anatomical changes that can occur in the tumor (shrinkage, progression) and organs at risk (OAR) (weight loss, air cavity filling, organs deformat ion, …), over the course of a treatment. In practice, ART requires repeated image acquisitions to capture the daily anatomy, to delineate the updated patient volumes, and to re-optimize the dose based on the current snapshot of the patient anatomy.
