Image-guided Radiation Therapy (IGRT)

Radiation oncologists at University of Wisconsin Carbone Cancer Center use image-guided radiation therapy, or IGRT, to deliver radiation more precisely to tumors that will change position between treatments due to movements while breathing.

IGRT involves radiation treatment guided by imaging, such as CT scan, ultrasound or X-ray, taken in the treatment room right before the radiation treatment is given.


This allows the physicians to see if the treatment field needs to be adjusted each day and helps target the radiation to the tumor more precisely while avoiding nearby healthy tissue.
