Radiation Therapy

Radiation therapy utilizes ionizing radiation in a strictly controlled environment to treat disease, primarily cancer. High energy x-rays, gamma rays, and electron beams are common forms of ionizing radiation used. Ionizing radiation can be administered using external beam therapy or by placing a radioactive material directly into a body tissue or cavity. The ultimate goal of radiation therapy is to destroy all abnormal cells while sparing the surrounding normal tissue as much as possible.

Radiation therapists deliver radiation therapy treatments, with a high degree of technical expertise, to patients as prescribed by a radiation oncologist according to established practices and standards. Other responsibilities and duties include reviewing prescription and diagnosis; performing CT simulation; constructing immobilization and treatment devices; educating patient/family; acting as liaison with physician and supportive care personnel; participating in quality and safety activities; and maintaining records, reports, and files. May assist in tumor localization and treatment planning.
