Preferred Name	Radiotherapy, Intensity-Modulated
Definitions	CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions. An approach of delivering intensity-modulated radiotherapy where dosage beams are delivered concurrently with gantry rotation. An arc-based approach to the delivery of intensity-modulated radiotherapy that uses a fan-beam of radiation in conjunction with a binary multileaf collimator.
