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

Intensity Modulated Radiation Therapy (IMRT) is a sophisticated form of radiation treatment that utilizes advanced technology to deliver precise doses of radiation to a tumor while minimizing exposure to surrounding healthy tissues. This technique involves the use of multiple fields or arcs, which are narrow beams of radiation that can be spatially and temporally modulated. The modulation allows for the adjustment of the intensity of the radiation beams, ensuring that the tumor receives a higher dose necessary for effective treatment, while the adjacent healthy tissues are spared from excessive radiation exposure. The use of dynamic multi-leaf collimators (MLC) further enhances the precision of the treatment by shaping the radiation beams to conform to the three-dimensional shape of the tumor. This targeted approach is crucial in improving treatment outcomes and reducing side effects associated with radiation therapy.
