What’s this procedure?

Image-guided radiation therapy (IGRT)

Image-guided radiation therapy (IGRT) takes frequent pictures during a course of therapy to improve the precision and accuracy of the radiation treatment.

With the patient positioned on the treatment table, machines that deliver radiation are equipped with special imaging technology that allow doctors to see the tumour immediately before, or even during, the time radiation is delivered.

Any necessary adjustments can be made to the patient’s position and the radiation beams.

It means doctors can more precisely target the radiation at the tumour and avoid damaging healthy surrounding tissue.
