[en] Advances in technology have helped to pave the way for techniques like image guided brachytherapy (IGBT) that are leading to better outcomes and offering a better quality of life for patients. While brachytherapy — a form of internal radiation treatment using radioactive sources — has been a common treatment for many cancers for more than 100 years, IGBT has only in the last 15 years been possible thanks to advances in medical imaging, treatment planning and dose delivery. IGBT is designed to maximize the radiation dose to kill cancer cells while minimizing the exposure of the surrounding healthy cells. It uses detailed 3D medical images to capture organ volume changes in order to tailor and optimize brachytherapy for patients’ needs.
