Image-guided radiation therapy (IGRT) is a kind of radiation therapy that implies imaging techniques during each treatment.
Radiation therapy is used with high-energy radiation beams to control cancer and noncancerous tumors. IGRT ensures the powerful radiation is narrowly focused on the treatment area by adding detailed images.
During IGRT, high-quality images are taken before each radiation therapy treatment session. IGRT makes it possible to use higher doses of radiation, which increases the probability of tumor control.
IGRT is the standard of care for radiation therapy treatment and is used to treat all types of cancer.
IGRT is used to treat all types of cancer, but it's ideal for tumors and cancers located very close to sensitive structures and organs.
High-quality images are taken before each radiation therapy treatment session and radiation therapy team compares these images to previously taken images, to determine if the tumor is in the correct position, to precisely target it with radiation.
