How does the Gamma Knife work?
For tumors, the very intense dose of radiation directed precisely to the tumor, causes the DNA and proteins in the cell to render themselves unable to divide. The tumor cells can then no longer live, and slowly die over time. The waste is then removed by circulating white blood cells. For AVMs, the radiation causes the blood vessels to thicken and scar until flow ceases. For trigeminal neuralgia, the protective covering or insulation around the pain nerves is destroyed, thus making the nerve unable to conduct an impulse of pain.
Utilizing advanced diagnostic imaging and three-dimensional treatment planning software, Gamma Knife delivers 201 precisely focused beams of gamma radiation to small targets inside the brain. Radiation is only delivered at a single, finely focused point where all 201 beams converge to treat the diseased tissue, while nearby healthy tissue is spared.
