What is intensity modulated radiation therapy?
– a form of three-dimensional conformal radiation therapy (3-D CRT) – delivers highly focused radiation beams to the tumor or to areas within the tumor. Treatment planning begins with three-dimensional CT computer imaging that conforms the radiation beams to the size and shape of the tumor(s). The beams of radiation can be controlled or “modulated” in intensity and are delivered with high-precision accuracy that lessens damage to surrounding healthy tissue.
