About the Treatment Method
Smart Beam Distribution and Protection
For example, in head and neck cancers, the tumor can grow in a curved shape, almost clinging to the spinal cord, salivary glands, and the eye. While the IMRT device delivers radiation, it gives a high dose of radiation to the thick part of the tumor, and the moment the beam hits the eye or salivary gland just behind it, it reduces the intensity of the dose to zero, saving the organ from blindness or dryness.
With advancing technology and VMAT (rapidly rotating devices) additions, IMRT sessions have become quite short. The patient completes their daily session usually within 10-15 minutes, including getting on and off the table.
They are different, but they are always used together. IGRT is the eyes that "see" the target (imaging); IMRT, on the other hand, is the weapon that adjusts the intensity of the bullet going to that target. In modern oncology, patients are treated with devices where both technologies (IMRT + IGRT) are combined.
