IMRT (Intensity Modulated Radiation Therapy)

Clinicians around the world are using Intensity Modulated Radiation Therapy (IMRT) to treat nearly every type of solid tumor. IMRT "paints" the radiation dose onto the tumor with pinpoint precision. It uses 3-D scans of your body to guide the beams of radiation to the tumor from many different angles. At each of these angles, the intensity of the radiation is varied (modulated) and the shape of the beam is changed to match the shape of the tumor. These adjustments enable the prescribed amount of radiation to be delivered to each part of the tumor, while minimizing exposure to the surrounding healthy tissue.
