Radiation Therapy X Rays
What is radiation therapy. Radiation therapy also called radiotherapy is a cancer treatment that uses high doses of radiation to kill cancer cells and shrink tumors.

At low doses radiation is used in x rays to see inside your body as with x rays of your teeth or broken bones.
Radiation therapy x rays. The gamma knife is a treatment option that uses radioactive cobalt sources to focus multiple beams of radiation on a small area. Orthovoltage x ray machines which produce higher energy x rays in the range 200500 kv. X rays make up x radiation a form of high energy electromagnetic radiationmost x rays have a wavelength ranging from 001 to 10 nanometers corresponding to frequencies in the range 30 petahertz to 30 exahertz 310 16 hz to 310 19 hz and energies in the range 100 ev to 100 kevx ray wavelengths are shorter than those of uv rays and typically longer than those of gamma rays.
But when talking about radiation and cancer risk it is often x rays and gamma rays that people think about. Other names for radiation treatment are radiation therapy radiotherapy irradiation or x ray therapy. This radiation was called deep because it could treat tumors at depths at which lower.
Purpose the purpose of. The highly focused gamma rays or x rays then converge on the tumor to treat it. The history of radiation therapy or radiotherapy can be traced back to experiments made soon after the discovery of x rays 1895 when it was shown that exposure to radiation produced cutaneous burnsinfluenced by electrotherapy and escharotics the medical application of caustic substances doctors began using radiation to treat growths and lesions produced by diseases such as lupus.
Linear accelerators can also be used to deliver stereotactic radiation therapy to the brain. Early radiation therapy machines produced x rays that were in the orthovoltage range between about 140 and 400 kilovolts. Radiation therapy uses high energy particles or waves such as x rays gamma rays electron beams or protons to destroy or damage cancer cells.
That treatment caused serious and often intolerable skin burnsmodern radiation therapy machines produce beams that are in the high energy megavoltage range more than 1000 kilovolts which allows the beam to penetrate tissues and treat deep seated tumours. Radiation therapy definition radiation therapy sometimes called radiotherapy x ray therapy radiation treatment cobalt therapy electron beam therapy or irradiation uses high energy penetrating waves or particles such as x rays gamma rays proton rays or neutron rays to destroy cancer cells or keep them from reproducing. 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.
Radiation is one of the most common treatments for cancer. Contact x ray brachytherapy also called cxb electronic brachytherapy or the papillon technique is a type of radiation therapy using kilovoltage x rays applied close to the tumour to treat rectal cancer. Superficial radiation therapy srt machines produce low energy x rays in the same energy range as diagnostic x ray machines 20 150 kv to treat skin conditions.
