T.L.S. Tang, Mohamad Fahdillah Rhani · Radiotherapy and Oncology · 2019
In conventional non-adaptive radiotherapy, we try to consider all possible positions and shapes of the target volume and the organs at risk (OARs) when making a treatment plan.In contrast, in adaptive radiotherapy, the treatment is adapted to account for internal anatomical changes, which may change from day to day, or even within a fraction.The adaptation can be based on anatomy, but can also be based on the dose that has already been delivered.The adaptation can be done off line between treatments, or online immediately before treatment.In conventional radiotherapy, imaging and contouring is performed at baseline.The generated treatment is delivered over the course of a treatment series.Ideally possible changes in anatomy that may be foreseen during treatment are included or in case of significant changes (eg.significant weight loss) the procedure is repeated,
