29 May 2024 at 12 pm GMT; Duration 1 hour
Organizer and Moderator: Eva Bezak, Vice President IOMP
Speaker: Alexandru Dasu
The Skandion Clinic, Uppsala, Sweden.
Department of Immunology, Genetics and Pathology, Uppsala University, Uppsala, Sweden.
Alexandru Dasu is the Chief Medical Physicist at the Skandion Clinic, the national proton therapy centre in Uppsala, Sweden and academically affiliated to Uppsala University. Alexandru Dasu studied Medical Physics at Umeå University, Sweden, where he also received a Ph.D. degree in 2001. He became a certified medical physicist in 2003 and throughout his career combined clinical activities with research and education. His main research interests include proton therapy, the evaluation of the risk for stochastic effects following radiation therapy, the modelling of the tumour response to radiation therapy, radiation dosimetry and quality assurance.
Abstract:
Radiation therapy is a multi-disciplinary, multi-step treatment using complex equipment and techniques to deliver ionizing radiation generally for cancer patients. Each step in the process can be subject to constraints and variation that can affect the fine balance between delivering enough dose to the target while keeping the doses to the normal tissues at acceptable levels. Indeed, variations above 5% of the dose can lead to significant changes in local control or complication rates, this worsening the effectiveness of the treatment. A rigorous quality assurance system is therefore needed to ensure that the accurate doses have been delivered in the defined volume within the scheduled time and with limited dose to surrounding normal tissues.
This presentation will review the rationale for quality assurance in radiation therapy, the particular requirements of radiation therapy versus radiation protection, the steps to build a quality assurance as well as examples of the steps allowing a continuous improvement of quality in radiation therapy.
Learning Objectives
After the presentation, the attendees should be able to understand the rationale for quality assurance in radiation therapy and the methodology for setting up a quality assurance program, as well as the relationship between quality assurance and quality controls.
