Intensity Modulated Radiation Therapy (IMRT)

IMRT is an advanced system for delivery of external radiation. This technique allows maximum radiation to be delivered to the tumor and the surrounding areas at risk for harboring cancer cells, while minimizing radiation to your nearby normal organs. IMRT essentially allows us to change the strength of different portions of the beam as it leaves the linear accelerator.

What is IMRT?

IMRT is a more precise type of radiation therapy. Traditional radiation employs a flat beam that targets the cancerous tumor, but because of the irregular shape of tumors, healthy surrounding tissue can be damaged as well.  IMRT takes advanced radiation therapy a step further allowing doctors to more precisely attack all parts of irregularly shaped tumors -- thereby reducing the risk of injury to healthy tissue while allowing the dose to the cancerous cells to be increased.  It uses sophisticated software and hardware to vary the shape and intensity of radiation delivered to different parts of the treatment area. It is one of the most precise forms of external beam radiation therapy available.
