IGRT - Image Guided Radiotherapy

IGRT is radiotherapy guided by imaging technology such as CT scans, MRI’s, or PET scans.

In TomoTherapy. clinicians use the system’s CTrue scans to verify the patient’s position, anatomy and tumour site at the time of treatment, helping ensure the accuracy of each treatment procedure.

The TomoTherapy treatment machine combines a CT scanner and an external beam radiotherapy machine. Part of the TomoTherapy machine rotates completely around the patient to take CT scans and give radiotherapy to a very localised area.

The machine takes pictures of the tumour just before each treatment session to allow the doctors to target the treatment very precisely. This reduces the damage to normal body tissues in the area. This treatment is also called helical tomotherapy.
