The CT simulator is utilized to ensure accurate mapping of the treatment area. The CT simulator creates 3D images that are used to precisely outline the tumor volumes so that your therapy team can meticulously plan a course of treatment, tailored specifically to your anatomy. Because radiation affects normal cells as well tumor cells, treatment teams carefully map out the area minimize damage to normal tissue.
High Dose Remote Afterloader
External Radiation or Brachytherapy can be delivered near or directly into a tumor using a High Dose Rate Afterloader. The high dose rate remote afterloading unit provides radiation therapy to a localized area. Typically, an applicator or catheter is used to deliver the radioactive source directly to the tumor. This unit provides a method of treating cancer that has not been available in the past.
Traditionally, a radioactive implant would have been performed under general anesthesia and required several days of hospitalization. However, with the HDR, this procedure is performed at our centers on an outpatient basis. Thus, both the risk of general anesthesia and the cost of an extended hospital visit are avoided.
Implants are the clinical use of encapsulated radioactive sources placed either temporarily or permanently into the tumor and surrounding structures which deliver radiation continuously over an extended period of time. Brachytherapy is used in the management of specific cancer sites where its physical advantage is a superior localization of the dose to the tumor volume.
Temporary implants include certain gynecological malignancies with treatments usually one to three days in duration in a hospital setting. Permanent implants include certain prostate cancers and are often done as an outpatient procedure.
