Preferred Name	Intensity-Modulated Radiation Therapy
Definition	An advanced form of 3-Dimensional Conformal Radiation Therapy (3D CRT) that involves the use of varying intensities of small radiation beams to produce dosage distributions that are more precise than those possible with 3D CRT./CDISC Definition: An advanced form of 3-Dimensional Conformal Radiation Therapy (3D CRT) that involves the use of varying intensities of small radiation beams to produce dosage distributions that are more precise than those possible with 3D CRT. (NCI)/NCI-GLOSS Definition: A type of 3-dimensional radiation therapy that uses computer-generated images to show the size and shape of the tumor. Thin beams of radiation of different intensities are aimed at the tumor from many angles. This type of radiation therapy reduces the damage to healthy tissue near the tumor.
