Definition

IMRT is a form of advanced  radiation therapy. In IMRT, the beam intensity varies across the treatment field, and numerous small beams with modulated intensities are irradiated through multiple ports to the target to ensure that a prescribed dose is homogeneously delivered to the target while a reduced dose is given to adjacent critical organs.
