Image Guided Radiation Therapy (IGRT)
Patients and their organs move; so do tumors. The motion that results simply
from breathing can cause a radiation beam to miss its target. Image-guided
radiation therapy is one of the most cutting-edge innovations in fighting
cancer. Using technology called an on-board imager, your doctor is able
to map the tumor's exact location at the time of treatment, and make
very fine adjustments to your position to greatly increase the precision
of your radiation treatment. Knowing exactly where the tumor is allows
clinicians to target only the tumor, sparing the healthy tissue nearby.
