31stereotaxic radiation therapy — A type of external radiation therapy that uses special equipment to position the patient and precisely deliver radiation to a tumor. The total dose of radiation is divided into several smaller doses given over several days. Stereotaxic radiation… …
32proton beam radiation therapy — A type of high energy, external radiation therapy that uses streams of protons (small, positively charged particles) that come from a special machine. Proton beam radiation is different from x ray radiation …
33radiation therapy — The use of high energy radiation from x rays, gamma rays, neutrons, protons, and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine outside the body (external beam radiation therapy), or it may come from… …
34total skin electron beam radiation therapy — TSEB radiation therapy. A type of radiation therapy using electrons that is directed at the entire surface of the body. This type of radiation goes into the outer layers of the skin, but does not go deeper into tissues and organs below the skin.… …

36external radiation therapy — A type of radiation therapy that uses a machine to aim high energy rays at the cancer from outside of the body. Also called external beam radiation therapy …
37external-beam radiation therapy — A type of radiation therapy that uses a machine to aim high energy rays at the cancer from outside of the body. Also called external radiation therapy …
38electron beam — ▪ physics stream of electrons (as from a betatron) generated by heat ( thermionic emission), bombardment of charged atoms or particles (secondary electron emission), or strong electric fields (field emission). Electrons may be collimated by …
39rotation therapy — in radiotherapy, circular movement of the patient or of the radiation source and beam around a fixed anatomical axis during a treatment exposure; it may entail complete, partial, or skip field exposure …
40electron beam — A stream of electrons (small negatively charged particles found in atoms) that can be used for radiation therapy …
