Image-guided radiotherapy (IGRT) is the use of real-time imaging before and during radiotherapy treatment to visualize tumor and normal tissue volumes and to improve precision and accuracy of the targeting during the treatment delivery. IGRT gives 3-dimensional “sight” to physicians, allowing them to better target tumors while minimizing the effect of radiation on surrounding tissues and organs.
Better Monitoring During Radiation Treatment
With IGRT, radiation oncologists possess tools that can better account for the uncertainties involved in setting up patients for fractionated radiation delivery. Additionally, IGRT allows for the monitoring of changes in tumor size, shape and position due to treatment and normal physiological processes such as breathing, bowel movements and other.
IGRT Image Guidance Technologies
As the advances of IGRT continue to be integrated into the radiation oncology clinic at the Cancer Center, our IGRT technologies include portal and radiographic imagers, kilovoltage and megavoltage cone-beam CT scanners and electromagnetic field tracking systems.
