What is intensity modulated radiotherapy?
Intensity modulated radiotherapy (IMRT) is a type of external beam radiotherapy. It is a high precision type of radiotherapy that uses computer controlled linear accelerators to deliver high dose radiation to cancerous tumours, while limiting the impact of radiation on healthy surrounding tissue.
By modulating, or controlling the radiation beams to the 3D mapped image of the tumour, therapists are able to target the tumour in varying dose intensity patterns.
