Intensity modulated radiation therapy, also
known as IMRT, is a type of radiotherapy that makes use of computer
controlled software designed to deliver specific and very precise doses
of radiation to specific areas within cancerous or malignant tumor
growth. At its most basic definition, this type of therapy can render
nearly 3-D or three dimensional images and shapes of a tumor by
controlling the intensity of flow of radiation beams.
IMRT basically prevents cancerous cells their ability to divide and replicate or grow, efficiently slowing or halting tumor growth. As such, radiation therapy is designed to destroy and kill cancerous cell growth.

Intensity
modulated radiation therapy is a type of 3-D computed tomography.
Computed tomography is also known as CT imaging. The 3-D computed
tomography technology is combined with precise calculations delivered by
computer analysis to determine specific doses and intensities of
radiation to be delivered depending on tumor shape and size. Such an
approach offers physicians the ability to tailor radiation doses on a
customized and individualized basis as well as minimizing damage of
surrounding or normal tissues.
To date, intensity modulated radiation therapy is used mainly to treat prostate cancers as well as cancerous growth found in the head, neck, and central nervous system. However, this type of technology has also begun to be used for treatments of thyroid, breast and lung cancers.

A variety of individuals are involved in the IMRT process, including
radiation therapists, oncologist, physicists and radiation therapy
nurses. Each of these individuals is responsible for the delivery of
exact radiation doses, while a person called a dosimetrist is
responsible for calculating the configurations necessary for the
technology to deliver adequate doses under the direction of the
radiation oncologist.
The equipment utilized to deliver intensity modulated radiation therapy has been described as roughly the size of a small car. The patient lays on a treatment table, and a piece of equipment called a linear accelerator emits radiation beams to the tumor from a variety of locations and positions. Sessions usually take 10 to 30 minutes.
