Image Guided Radiation Therapy (IGRT)

IGRT is the use of sophisticated technologies used to pinpoint the exact location of a targeted tumor while the patient is being treated. The precision of this technology is crucial to treatments because tumors are not stationary. Tumors can move during treatment due to normal physiological processes (ie: Breathing, organ movement, and flatulence).  IGRT uses advanced techniques to verify the patient’s exact position and the tumor’s precise location during treatment. Knowing the exact location of the tumor allows the Radiation Oncologist to reduce the amount of tissue irradiated, which spares the surrounding normal tissue and irradiating only the tumor. Irradiating less normal tissue reduces the toxicity, improves quality of life for the patient and makes it possible for a higher does to be given to the tumor.
