Intensity
Modulated Radiation Therapy (IMRT )
The most precise form of radiation therapy
available that delivers high doses of radiation directly
to cancer cells in a very targeted way. IMRT involves varying
(or modulating) the intensity of the radiation being used
as treatment for cancer. IMRT uses computer-generated images
to plan and deliver more tightly focused radiation beams
to cancerous tumors than is possible with conventional
treatment. With this capability, clinicians can deliver
a precise radiation dose that “paints” or
conforms to the shape of the tumor, while significantly reducing
the amount of radiation to surrounding healthy tissue. Consequently,
the rate of tumor control can be increased while considerably
reducing adverse side effects.
With IMRT, tumors that might have
been considered untreatable in the past due to the close proximity
to vital organs and structures are now treatable.
