Image-guided Radiation Therapy (IGRT)

What is Image-guided Radiation Therapy (IGRT)?

Image-guided radiation therapy (IGRT) is a way of using X-rays and images (scans) of your body to guide your individual treatment. The X-rays and scans show the size, shape and position of your cancer. This specifically targets the movement of tumor due to organ motion.

Focused dose of radiation is delivered precisely to the cancer. The surrounding healthy tissue is given as low a dose as possible to reduce the risk of injury to these tissues.

Why do you need Image-Guided Radiation Therapy (IGRT)?

By using IGRT, doctors can target the radiation more accurately. As treatment is personalised, the planning can take a bit longer than for some other treatments, and each therapy session may be a bit longer.

As IGRT is able to track changes to your cancer throughout treatment, your treatment plan can be altered at any stage. This can result in:

  • Better treatment
  • More precise and effective radiation therapy
  • Fewer side effects
