The ROSEIS platform has been developed under the umbrella of the ESTRO Radiation Oncology Safety and Quality Committee and a sub-group is responsible for the development and maintenance of the platform. Consistent with the membership of the ROSQC this sub-group is multidisciplinary to reflect the disciplines primarily responsible at the different steps throughout the radiotherapy process.


Mary Coffey is an Adjunct Associate Professor in the Discipline of Radiation Therapy and previous Head of Discipline. She was a member of the ROSIS founder group and is currently chair of the Radiation Oncology Safety and Quality Committee of ESTRO.

ESTRO, the European SocieTy for Radiotherapy & Oncology, is a non-profit and scientific organisation that fosters the role of Radiation Oncology in order to improve patients’ care in the multimodality treatment of cancer.


Elekta is a leading innovator of equipment and software used to improve, prolong and save the lives of people with cancer and brain disorders. Our treatment solutions and oncology informatics portfolios are designed to enhance the delivery of radiation therapy, radiosurgery and brachytherapy, and to drive cost efficiency in clinical workflows.


Varian is a leader in developing and delivering cancer care solutions, including hardware and software for planning and delivering radiotherapy, radiosurgery, proton therapy and brachytherapy. In this capacity, Varian is focused on safety issues throughout the product life cycle. Our attention to patient safety starts with how we design and develop new products and subject them to state-of-the-art verification and validation testing based on industry standards and best practices. It continues through a rigorous and ongoing postmarket surveillance program that collects extensive amounts of data so that we can identify any issues that could affect patient safety. As a result, Varian radiotherapy systems incorporate multiple and redundant safety features designed to ensure that clinical teams can use them safely and effectively.
