Intensity Modulated Radiation Therapy (IMRT) is a type of radiation therapy treatment technique that involves the continuous changing (modulation) of the radiation beam. During treatment the Linac will go to the treatment angle and deliver a beam of radiation. During the delivery of the radiation beam, the Linac will alter the intensity of the radiation and also the shape of the radiation beam so that it is conforming around the target. This shaping reduces the amount of radiation the surrounding healthy and normal tissue receive while directing more dose to the cancer. The Linac will deliver radiation at multiple angles around you to precisely sculpt the radiation dose.
