Intensity modulated treatment delivery, single or multiple fields/arcs,via narrow spatially and temporally modulated beams, binary, dynamic mlc, per treatment session G6015

Intensity-modulated radiation therapy (IMRT) is a type of cancer treatment. It uses advanced technology to manipulate photon beams of radiation to conform to the shape of a tumor. IMRT allows for the radiation dose to conform more precisely to the three-dimensional shape of the tumor by modulatingâ€”or controllingâ€”the intensity of the radiation beam. This can result in better tumor control and less harm to healthy tissue.
