Brachytherapy Applicators, Automated, Interstitial/Intracavitary, Tandem/Ovoid
Definition : Automated brachytherapy applicators designed to deliver therapeutic radioactive sources to, retrieve them from, and/or hold them in the uterine cavity. The applicator consists of a hollow metal tube (i.e., tandem), which temporarily holds the radioactive source, and two semioval, cuplike structures (i.e., ovoids) placed on either side of the cervix. The applicator holds the radioactive source during treatment and includes tiny shields to reduce the radiation dose to the rectum and bladder. The tandem is fixed inside a hollow plastic tube (i.e., Smitt sleeve) previously inserted into the uterine cavity. Tandem/ovoid interstitial/intracavitary applicators are used to treat cervical cancer.
