IMRT is an advanced form of 3D therapy.
It uses Turville Bay’s Linear accelerator, a
computer-driven machine, to actually move around the
patient as it delivers radiation. In addition to shaping
the beams and aiming them at a specific area from several
angles, the intensity (strength) of the beams can be
adjusted to minimize the dose reaching the most sensitive
normal tissues. This allows doctors to deliver an even
higher dose to the cancer areas while avoiding normal
tissue.
From the American
Cancer Society
“Currently,
IMRT is being used to treat cancers of the prostate,
head and neck, breast, thyroid and lung, as well
as in gynecologic, liver and brain tumors and lymphomas
and sarcomas.”
