IGRT is a "State of the Art Cancer Treatment" that delivers high doses of radiation directly to cancer cells in a very targeted way, much more precisely than is possible with conventional radiotherapy. IMRT/IGRT can deliver higher radiation doses directly to cancer cells while sparing more of the surrounding healthy tissue. This has important advantages in oral cancers as it allow the beams to hit their target area while missing the surrounding structures such as the salivary glands.
IMRT/IGRT uses Computer- Generated images to plan, and then deliver tightly focused radiation beams to cancerous tumors. Clinicians use it to exquisitely "Paint" the tumor with a precise radiation beam that conforms as closely as possible to the shape of the tumor. IGRT can be used to treat tumors that might have been considered untreatable due to close proximity of vital organs and structures. Treating such tumors requires tremendous accuracy. In the case of head and neck tumors, IMRT/IGRT allows radiation to be delivered in a way that minimizes exposure of the spinal cord, optic nerve, salivary glands or other important structures. In the case of prostate cancer, exposure of the bladder or rectum can be minimized. IMRT/IGRT is were to treat tumors in the brain, breast, head & neck, liver, lung, nasopharynx, pancreas, prostate, and uterus A powerful Computer Program optimizes a treatment plan based on the physician's dose instruction, and information about tumor size, shape and location in the body. A medical liner accelerator, equipped with a special device called a MultiLeaf Collimator that shapes the radiation beam, delivers the radiation in accordance with the treatment plan. The equipment can be rotated around the patient to send radiation beams from the most favorable angles for giving the tumor a high dose while preserving important healthy tissues.
