What is Intensity modulated radiation therapy?
IMRT is a type of conformal radiation therapy. It is delivered using a machine called a linear accelerator (LINAC). Use of IMRT allows the shape and intensity of the radiation beam to change while treatment is delivered.1,2
IMRT is offered to some patients with cancer, as it provides an opportunity to precisely target and treat the cancer while protecting the surrounding healthy organs and/or tissue from those high doses of radiation.1,2
