Image Guided Radiation Therapy
Image Guided Radiation Therapy (IGRT) is an advanced form of radiation treatment that combines imaging and treatment capabilities on a single machine. Because tumors can move, IGRT allows a radiation oncologist to see and track the tumor at the time of treatment, and to make very fine adjustments to a patient’s position so as to greatly increase the precision and accuracy of radiation therapy treatment. Knowing exactly where the tumor is allows clinicians to irradiate only the tumor, sparing the surrounding normal tissue. This accuracy results in higher radiation doses to the tumor and thereby increases the likelihood of controlling or eliminating the cancer.
