What is IMRT?
Intensity modulated radiation therapy (IMRT) is a state-of-the-art radiation delivery system that is used to treat difficult-to-reach tumors.
How it works
IMRT uses advanced software to plan a precise dose of radiation, based on tumor size, shape and location. A computer-controlled device called a linear accelerator delivers radiation in sculpted doses that match the exact 3D geometrical shape of the tumor, including concave and complex shapes.
With IMRT, our radiation oncologist can adjust the intensity of radiation beams across the treatment area as needed with laser accuracy. This means we can deliver higher radiation doses than traditional radiation therapy methods, while minimizing exposure to healthy tissues.
Because of its greater degree of accuracy, IMRT may be a treatment option for patients who have reached the maximum allowable dose of conventional radiation therapy and have a recurrent tumor in the treated area.

IMRT for brain cancer
Because of its accuracy, IMRT helps to reduce damage to healthy brain tissue and minimize side effects. As a result, IMRT is particularly useful when treating tumors that are close to critical structures in the brain, such as the brain stem or the nerves of the eyes.
Compared to standard radiotherapy, IMRT allows our radiation oncologists to use higher doses of radiation from any angle, and shape radiation beams to match the contour of the brain tumor. At the same time, IMRT helps to spare healthy brain tissues and reduce side effects.
