IMRT is a specialized form of 3 dimensional external beam radiation therapy that allows radiation to be more exactly shaped to fit your tumor.
With IMRT the radiation beam can be broken up into many "beamlets" and the intensity of each beamlet can be adjusted individually.
Using IMRT it may be possible to further limit the exact amount of radiation that is received by normal tissues that are near the tumor. In some situations, this may also allow a higher dose of radiation to be delivered to the tumor, increasing the chance of a cure.
Radiation Oncology HealthCare doctors are implementing IMRT with real time image guidance utilizing either the TomoTherapy Hi Art System® , Cone Beam technology or Varian RapidArc System .
