Image Guided Intensity Modulated Radiation Therapy (IGIMRT, IG-IMRT) represents a significant technological advance and a new paradigm for the radiotherapeutic management of cancer. IMRT is capable of sparing sensitive structures of a high-dose radiation, by shaping the radiation even if only several millimeters away from the tumor. Image Guided Intensity Modulated Radiation Therapy (IGIMRT, IG-IMRT), the latest advancement consists of IMRT combined with Image Guidance. A scan is performed just prior to treatment to adjust for positional or anatomical changes. This allows for the most accurate and precise radiation treatments possible.
