Imrt external beam
WitrynaIntensity-modulated radiation therapy (IMRT) uses multiple small radiation beams to precisely irradiate a tumor. In addition to conform to the tumor volume like 3D … Intensity modulated radiation therapy (IMRT) is an advanced radiotherapy technique used to minimize the amount of normal tissue being irradiated in the treatment field. In some systems this intensity modulation is achieved by moving the leaves in the MLC during the course of treatment, thereby delivering a radiation field with a non-uniform (i.e. modulated) intensity. With IMRT, radiati…
