The Lourdes Regional Cancer Center has a new tool in it's cancer fighting
arsenal, Intensity Modulated Radiation Therapy. IMRT is a type of
three-dimensional radiation therapy that improves the targeting of radiation
therapy treatments, decreasing damage to normal tissues. This noninvasive
procedure pinpoints the delivery of radiation to the patient by using a
computer system to change the intensity of radiation beams, creating a
clinically optimal treatment plan - one that maximizes the dose to the tumor
while sparing the surrounding tissues.
Intensity Modulated Radiation Therapy is the most technologically advanced
treatment method available in external beam radiation therapy. IMRT uses
computer-generated images to match a radiation dose to the size and shape of a
patient's tumor. Rather than having a single large radiation beam pass through
the body, with IMRT, the radiation is effectively shaped in order to conform
to the size and shape of the tumor. With laser accuracy, these beams enter the
body from many angles and target the cancer. This results in a high dosage of
radiation to the tumor and a lower dosage to the surrounding healthy tissues.
IMRT is performed on an outpatient basis. It is most beneficial for
patients who need high-dose radiation therapy in areas closely located to
sensitive or essential organs, but all types of cancer can benefit from IMRT.
