Radiation Therapy

Radiation oncology is the specialty of medicine in which ionizing radiation is used to treat both malignant and benign conditions. The term radiation therapy (RT) is used, in part, as a differentiator from diagnostic radiation. In radiation oncology, treatment is provided with a team-based approach by physicians, nurses, physicists, dosimetrists, and radiation therapists. Dosimetrists perform the initial planning and mapping of the radiation fields. Radiation therapists deliver the treatment with external beam radiation therapy machines.
