intensity-modulated radiation therapy (IMRT)

a specialized method of delivering radiation so that the beam enters the body from many different angles to get to the tumor with pinpoint accuracy while sparing much of the surrounding healthy tissue.

IMRT

Intensity-modulated radiation therapy Radiation oncology A format for delivering high-dose RT to regions–eg, nasopharynx, that are surrounded by radiation-sensitive areas; in IMRT, a broad radiation field is divided into hundreds of small pencil beams, the intensity of which is determined by computer optimization
