Radiation Oncology Therapeutic
Typical Use
Place radioactive sources within or adjacent to tumors for localized radiation therapy.
Description
Devices such as intracavitary tandems and ovoids, interstitial needles, or surface molds used to position radioactive sources directly in or near malignant tissue to deliver high local radiation doses while limiting exposure to surrounding organs, commonly used in gynecologic, prostate, and head and neck cancers. Applicator selection, imaging based planning, and precise source loading are critical to achieve therapeutic goals and minimize complications such as tissue necrosis or radiation cystitis. Brachytherapy requires coordination of radiation oncology, medical physics, and procedural teams for safe insertion, dosimetry, and posttreatment care.
