WebMar 9, 2024 · Intensity-modulated radiation therapy, also called IMRT, is an advanced type of radiation therapy. Radiation therapy uses powerful energy beams to kill cancer cells. The energy can come from X-rays, protons or other sources. With IMRT, the beams of radiation are carefully customized. The beams are shaped to match the shape of the cancer.
