Learn about the basis AND latest developments in stereotactic body radiotherapy and cranial stereotactic radiosurgery. Understand the physical and technical requirements and discuss ways to establish a multi-professional clinical stereotactic programme. A blended learning concept with combination of state-of-the-art pre-recorded lectures, livestreamed theoretical classes and practical workshops addresses clinicians, physicists addresses the needs and interests of individuals with various experience in stereotactic radiotherapy: “How to start a SBRT program?” for individuals with no or limited experience. AND “How to continuously improve and update an existing SBRT program to most recent developments and evidence” for individuals with advanced experience. The online course will be divided into six-modules online, each focusing on one clinical indication and one medical-physics aspect of SBRT. Consequently, the course aims to simultaneously provide a state-of-the-art knowledge about stereotactic treatment and discuss the latest advancements in the field.
