UMD: Systems designed to perform radiotherapy by administering a radioisotope directly into tissue (e.g., tumor, intravascular) to prevent or reduce tissue proliferation. These systems typically include a radiation delivery unit, a source safe, applicators, and controls. Brachytherapy systems (e.g., remote afterloading systems) are used to treat cancer and other types of abnormal proliferative tissue (e.g., intravascular restenosis), minimizing the radiation dose to surrounding tissue and avoiding hospital staff exposure to radiation.
