Intensity-modulated radiation therapy (IMRT) is an advanced radiation therapy technique used to treat cancer and noncancerous tumors.
Intensity-modulated radiation therapy (IMRT) is an advanced mode of high-precision radiotherapy that uses computer-controlled linear accelerators to deliver precise radiation doses to the tumor or specific areas. IMRT allows the radiation dose to conform more precisely to the tumor's three-dimensional (3-D) shape by modulating—or controlling—the intensity of the radiation beam in multiple small volumes. IMRT also allows higher radiation doses to be focused on the tumor while minimizing the amount to surrounding typical critical structures.
IMRT is a treatment option with several advantages, including modulating radiation intensity to the tumor's unique size and shape, acurately delivering high-dose radiation, potentially increasing treatment effectiveness, avoiding radiation to healthy organs and tissues, reducing side effects and complications.
IMRT is often used to treat prostate cancer, head and neck cancers, lung cancer, brain cancer, gastrointestinal cancers, and breast cancer because these tumors tend to be close to critical organs and tissues in the body.
