Gamma Ray Radiation Therapy

In contrast to brachytherapy sealed source radiotherapy and unsealed source radiotherapy in which the radiation source is inside the body external beam radiotherapy directs. Gamma rays are another form of photons used in radiotherapy.

At low doses radiation is used in x rays to see inside your body as with x rays of your teeth or broken bones.

Gamma ray radiation therapy. Other names for radiation treatment are radiation therapy radiotherapy irradiation or x ray therapy. Gamma rays are produced spontaneously as certain elements such as radium uranium and cobalt 60 which release radiation as they decompose or decay. But when talking about radiation and cancer risk it is often x rays and gamma rays that people think about.

Gamma radiation is a highly energetic electromagnetic radiationit appears often with alpha and beta radiation. In this type of decay an excited nucleus emits a gamma ray almost immediately upon formation. Radiation therapy also called radiotherapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors.

Gamma rays are the same type of ionizing radiation like x rays but differ in their origin. The first gamma ray source to be discovered was the radioactive decay process called gamma decay. Gamma knife radiosurgery is able to accurately focus many beams of gamma radiation on one or more tumors.

Paul villard a french chemist and physicist discovered gamma radiation in 1900 while studying radiation emitted from radium. There are many different types of radiation from the light that comes from the sun to the heat that is constantly coming off our bodies. External beam radiotherapy ebrt is the most common form of radiotherapy radiation therapythe patient sits or lies on a couch and an external source of ionizing radiation is pointed at a particular part of the body.

The forms of ionizing radiation relevant to the treatment of cancer are x rays gamma rays and particulate radiation beams. Gamma knife therapy like all radiosurgery uses doses of radiation to kill cancer cells and shrink tumors delivered precisely to avoid damaging healthy brain tissue. Therapeutic use of gamma rays.

Each element decays at a specific rate and gives off energy in the form of gamma rays and other particles. What is radiation therapy. Directly ionizing radiation eg a beam of protons alpha particles or beta particles causes direct disruption of the atomic or molecular structure of the tissue through which it passes.

Those forms of radiation are either directly ionizing or indirectly ionizing. Radiation therapy uses high energy particles or waves such as x rays gamma rays electron beams or protons to destroy or damage cancer cells. Radiation is one of the most common treatments for cancer.

Gamma knife radiosurgery like other forms of stereotactic radiosurgery srs is not surgery in the traditional sense because there is no incision. Gamma knife radiosurgery is a type of radiation therapy used to treat tumors vascular malformations and other abnormalities in the brain.
