Imrt arc

WitrynaOriginally proposed as intensity-modulated arc therapy (IMAT) in 1995 as an alternative to tomotherapy, the idea of VMAT is to optimize the treatment plan in many angles, … WitrynaIMRT sends various doses of radiation toward a tumor across multiple smaller beams instead of using a single radiation beam. This technique allows healthcare providers to direct high doses of radiation toward tumors without exposing the surrounding healthy tissue to harmful amounts of radiation.
