Intensity-Modulated Radiotherapy (IMRT)

Intensity-Modulated Radiotherapy (IMRT) is a form of external beam radiotherapy that uses linear accelerators to deliver multiple small radiation beams to a tumour.

It allows shaping of the radiation dose to improve the targeting of the tumour and minimise the radiation dose to the surrounding normal organs.

This therapy is mainly used where a tumour is situated close to normal tissues that have a high risk of damage from radiation.

IMRT is available where necessary in all St Luke's Radiation Oncology Network (S.L.R.O.N.) centres.
