IMRT - Intensity Modulated Radiotherapy
IMRT involves changing the size, shape, and intensity of the radiation beam to conform to the size, shape, and location of the patient’s tumour. The TomoTherapy radiotherapy treatment systems use a patented multi-leaf collimator to shape the radiotherapy area so that it precisely conforms to the shape of the tumour and it varies the intensity of the radiation beam during each treatment.

IMRT focuses a higher radiation dose on the tumour but gives a much smaller dose to surrounding normal tissues than standard radiotherapy. So, side effects may be lower than with standard radiotherapy treatment.
