IMRT | Intensity Modulated Radiation Therapy
Intensity Modulated Radiation Therapy, or IMRT radiation, is a revolutionary delivery technology that allows the Radiation Oncologists at Advanced Radiation Centers to conform, or shape, the radiation high dose region into a highly 3-Dimensional manner.
Before IMRT radiation existed, a radiation plan involved two to five or more beams, which just intersected into one another at the tumor area. Now, IMRT takes each one of those beams and breaks it up into thousands of individual tiny “beamlets” providing the ARC physicians with a “full color palette” of radiation intensities to work with, as opposed to just shades of grey, so to speak. That, in turn, provides the doctors with the ability to shape the radiation to the exact 3-D shape of the target. Thus, Intensity Modulated Radiation Therapy can keep high doses of radiation away from tissues and organs that don’t need it, ultimately reducing side effects to the patient.
Combined with Image Guided Radiation Therapy, or IGRT, targeting IMRT radiation enables the radiation dose to zero in on the tumor without significant side effects for patients with breast cancer, prostate cancer, lung cancer, head and neck cancers, as well as many other tumor sites.
