Intensity-modulated radiation therapy

Intensity-modulated radiation therapy (IMRT) is one of the recent advances in the delivery of radiation that allows the radiation be directed to the tumor or target with very little collateral impact to surrounding tissues or organs. IMRT uses advanced software to evaluate tumor size, shape and location to design an individualized radiation treatment plan.

Tumors can often be irregularly shaped and these odd shapes can pose problems when treated with radiation treatments that deliver radiation in straight lines. The software used in IMRT matches the exact 3D shape of the tumor to deliver radiation with greater precision.

IMRT modifies the intensity of the radiation within each of the radiation beams and allows delivery of higher doses of radiation to tumors, especially those near vital areas, while lowering doses to nearby healthy tissue. Because IMRT conforms the radiation dose to the target area, it is typically used to treat difficult-to-reach tumors
