Intensity modulated rt
WebNov 6, 2024 · Intensity modulated radiotherapy (IMRT) is a type of conformal radiotherapy. Conformal radiotherapy shapes the radiation beams to closely fit the area of cancer. You can have IMRT on a standard radiotherapy machine, called a linear accelerator (LINAC). WebThere are two main types of radiation therapy. External radiation therapy is when a beam of radiation is directed into the body. It may also be called x-ray therapy, 3D conformal radiation, intensity-modulated radiation therapy (IMRT), cobalt, photon, or proton therapy. Internal radiation therapy is when a radioactive source is placed inside ...
