Image-guided radiation therapy (IGRT)

About this approach

IGRT uses imaging before or during radiation sessions to confirm the tumor and patient position. It can help account for daily setup differences and, in some settings, organ or tumor motion. IGRT is part of radiation delivery and is often combined with IMRT, SBRT, or other techniques.

Where it fits: Imaging used to verify and adjust radiation treatment position

Where this treatment is used

Image guidance is established in modern radiation oncology, but the imaging method and frequency should match the treatment site and precision required.

Procedure and practical considerations

Additional imaging can add small radiation exposures and treatment time. Positioning devices may be uncomfortable, and some sites require implanted markers or contrast. The team should explain how images are used and when a treatment is adjusted or delayed.
