High Dose Rate

High dose rate brachytherapy is a type of internal radiation therapy that delivers radiation from implants placed close to, or inside, the tumors in the body. Because cancer often affects organs and other essential structures, it is important for radiation treatment to be tightly focused on tumors to minimize serious side effects. This technique ensures the maximum radiation dose is given to cancerous tissues, while minimizing exposure to the surrounding healthy tissue.
