IMRT Radiation Abbreviation

Intensity Modulated Radiation Therapy

Intensity Modulated Radiation Therapy that delivers non-uniform exposure across the beam's eye view rather than an open field. This type of treatment can be delivered with a machined compensator (rare outside of community clinics), linear accelerator Multi-Leaf Collimator leaves or Tomotherapy binary leaves. The IMRT plan is usually (but not always i.e. breast tangents with control points) developed with an inverse treatment planning system.
