Intensity Modulated Radiation Therapy

Intensity-modulated radiation therapy (IMRT) is an advanced type of three-dimensional radiation that conforms to the shape of a tumor. It uses sophisticated software and hardware to vary the shape and intensity of radiation delivered to different parts of the treatment area. It is one of the most precise forms of external beam radiation therapy available.

 

It uses hundreds of small radiation beams of varying intensities to precisely radiate a tumor. The radiation intensity of each beam is controlled, and the beam shape changes hundreds of times during each treatment. As a result, the radiation dose bends around healthy tissues in a way not possible with other techniques.

 

Doctors usually give a series of IMRT treatments over 4-8 weeks. The number of treatments depends on the size, location, and the type of cancer; the person's health, and the other cancer therapies taken . Doctors use CT scans, MRI scans and positron emission tomography (PET) scans to create a treatment plan that targets just the tumor. During treatment, special head frames or supports may keep the body from moving.
