Session

Overview: With increasing use of SBRT, working groups were established at the ESTRO 2021 physics workshop on harmonisation and standardisation of SBRT planning and delivery in order to better understand current practice and issue guidance on the technical implementation of this technique. Planning, delivery and dosimetry reporting for SBRT clinical trials was also evaluated to assess whether enough information was provided to interpret the data and reproduce the same processes outside the trial setting. Both working groups report their findings.
