Intensity-Modulated Radiation Therapy (IMRT) is an advanced form of radiation therapy used to treat cancer. It allows doctors to deliver precise doses of radiation to tumors while minimizing exposure to surrounding healthy tissues. This technique uses computer-controlled linear accelerators to modulate the intensity of the radiation beams, adapting them to the shape and size of the tumor. IMRT is particularly beneficial for treating complex tumors located near critical organs. By adjusting the radiation intensity, it can effectively target the cancer cells while reducing side effects. This personalized approach enhances treatment effectiveness and improves patient outcomes.
