Intensity-modulated radiation therapy (IMRT) is an advanced type of radiation therapy that is used to treat cancer and benign tumours. Beams of radiation are controlled to conform to the shape of your tumour.
Many small radiation beams of varying intensities are used to treat your tumour precisely. The radiation intensity of each beam is controlled, and the beam shape changes throughout each treatment.
The aim of IMRT is to reduce the amount of radiation to your healthy tissues and limit the side effects of treatment.
