IMRT

Intensity-modulated radiation therapy (IMRT) is a type of radiation therapy that uses advanced technology to precisely deliver radiation to a tumor while sparing nearby healthy tissue. It is commonly used to treat various types of cancer, including prostate cancer, head and neck cancer, and lung cancer.

in imrt, the radiation beam is broken down into many small beamlets, and the intensity of each beamlet can be adjusted individually to deliver different amounts of radiation to different parts of the tumor. this allows for a more precise targeting of the tumor while minimizing exposure to healthy tissue, reducing the risk of side effects and improving treatment outcomes. radiation therapy uses energy from the radiation to damage the dna in cancer cells, preventing them from growing and dividing. the radiation is carefully targeted to the tumor or cancerous area, while minimizing the exposure of nearby healthy tissue.the treatment itself is painless and usually takes only a few minutes. patients usually receive radiotherapy over a period of several weeks, with each treatment session lasting only a few minutes.
