Image-guided radiation therapy (IGRT)
Uses a variety of imaging techniques, including X-ray, CT, and ultrasound, to help focus radiation beams more precisely. It is used to treat cancerous and noncancerous tumors, especially those in difficult or sensitive areas.
Intensity-modulated radiation therapy (IMRT)
Allows higher-dose beams of radiation to be delivered to tumors while lowering the dose to the surrounding tissue.
