Image Guided Radiation Therapy (IGRT)

Image Guided Radiation Therapy or IGRT, helps to improve the delivery of radiation. With the intention to deliver the best, MGCH & RI uses Image Guided Radiation Therapy (IGRT). It is one of the most cutting-edge innovations in cancer technology available.

The linear accelerator is an integrated imaging and workflow solution that offers a comprehensive portfolio of image-guided and advanced treatment delivery protocols, including in-room CT imaging capabilities. IGRT involves conformal radiation treatment guided by a CT scan taken in the treatment room just before the patient is given the radiation treatment.

Tumors often move, because of breathing and other movements in the body. IGRT allows our doctors to locate and track the tumor at the time of treatment. With this technology, we can deliver precise radiation treatment to tumors that may shift as a result of breathing and movement of the bladder and bowels.

This also allows our radiation oncologists to make technical adjustments when a tumor moves outside of the planned treatment range. As a result, the radiation treatment is targeted to the tumor as much as possible, helping to limit radiation exposure to healthy tissue and reduce common radiation side effects.

Imaging in the treatment room during the course of radiation is referred to as Image guided radiation therapy.
