Recently, in vivo radiobiological experiments have shown that irradiation with electron beams, with ultra-high dose per pulse, may dramatically reduce adverse side effects while being equally efficient for tumour control as conventional irradiation. Extreme dose rates are delivered by laser-based accelerators, which are the next generation of accelerators for radiotherapy. These accelerators may facilitate the development of more efficient therapeutic techniques and cost-effective healthcare. Pulses with dose rate orders of magnitudes higher than those in conventional radiotherapy present significant metrological challenges, which need to be addressed to enable the translation of these novel radiotherapy techniques into clinical practice.
This is a joint research project carried out in the framework of the European Metrology Programme for Innovation and Research (EMPIR) (see:http://www.euramet.org/research-innovation/empir/). The EMPIR initiative is co-funded by the European Unions's Horizon 2020 research and innovation programme and the participating states. METAS is one of the project partners in the project.
