At the international level, ESTRO and the European Federation of Organizations for Medical Physics (EFOMP), have recently published the 3rd version of the Core Curriculum for Medical Physics Experts in Radiotherapy. The aim is to support harmonization of training and cross-border mobility of medical physics experts in Europe. In addition, new developments in the field of radiation oncology have been included in this updated core curriculum.
