What is "IMRT"?
IMRT stands for Intensity Modulated Radiation Therapy. It is a sub-type of 3-D conformal therapy. This is one of the latest technologies in radiation oncology. It gives the radiation oncologist a way to deliver high doses to the cancer, while avoiding sensitive normal organs.
IMRT allows the radiation oncologist to sculpt the radiation beams much more precisely than with conventional 3-D conformal therapy. IMRT is used when a radiation sensitive organ is nearby the cancer, or when trying to give a very high dose to a tumor. IMRT is frequently used for head and neck cancers and prostate cancer.
