How does the Gamma Knife? work?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...The Gamma Knife Perfexion? precisely focuses 192 beams of gamma radiation on a specific target area of the brain, with each beam originating from a slightly different point. Highly sophisticated computer software is used to determine the size, location and shape of the area to be treated. Only at the point where all 192 beams cross is enough radiation delivered to affect the diseased tissue, while sparing surrounding tissue.
Related QuestionsHow quickly will the Gamma Knife treatment work?
Gamma Knife of Spokane - Frequently Asked QuestionsThe effects of the Gamma Knife depend on the type of target - for most metastatic tumors, they respond within a few weeks or months. Some tumors that are slow growing, may take longer to respond. The overall goal of Gamma Knife radiosurgery is tumor control by using radiation to halt tumor growth by altering the DNA structure of the cancer cells, preventing these cells from reproducing.
Related QuestionsWhat makes the Gamma Knife treatment superior to other treatments?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...It is precise. Its effects on surrounding brain and other critical neural and vascular structures are minimized. It is safe - the design of the Department of Neurosurgery's Gamma Knife unit meets the rigorous standards for safety and efficacy set by the U.S. Nuclear Regulatory commission and patients do not face the risks associated with open-skull procedures or general anesthesia. The Gamma Knife Perfexion is also highly effective - its success rate is unprecedented.
Related QuestionsWho can be treated with the Gamma Knife?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...This noninvasive technology treats patients with abnormalities that are located within the brain or that are too close to delicate structures and blood vessels (though it is most effective on targets less than four centimeters in size). Almost a third of all the patients treated with the Gamma Knife since 1968 have sought relief from blood vessel problems (i.e. AVMs). Nearly two-thirds were treated for brain tumors, including cancer, glial tumors and rarer types of tumors.
Related QuestionsWhy is it called the Gamma Knife if there are no incisions made?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...The individual beams of gamma radiation are not strong enough to damage any tissue as they travel through the skull to the treatment site. At the site, the beams join together pecisely to act in the same way a surgical "knife" would to treat the abnormality.
Related QuestionsIs Gamma Knife treatment safe?
Gamma Knife Radiosurgery Center - - University of Arkansas f...The Gamma Knife allows non-invasive brain surgery to be performed with extreme precision while sparing healthy tissues surrounding the targeted treatment area. Also, because neither a surgical incision nor general anesthesia is required, the risks usually involved with open brain surgery, such as hemorrhage or infection, may be reduced. Hospitalization is rarely required and recovery time is minimal.

Related QuestionsGamma Knife Radiosurgery Center - - University of Arkansas f...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.Related Questions
GammaKnife - FAQGamma Knife? surgery is a unique process that utilizes 201 extremely precise gamma beans to focus and treat a specific area in the brain. The patient wears a helmet-like device called a collimator, which directs the beams to simultaneously merge at a single focal point. Sophisticatedly merged together with pinpoint precision, the beams work similar to a magnifying glass in the sun. Detailed imaging, high-tech equipment and a specialized medical team work in conjunction.Related Questions
FAQ Gamma Knife - The Gamma Knife Center of Methodist Hospit...Through advanced imaging and three-dimensional planning techniques, Gamma Knife Radiosurgery delivers multiple, very narrow beams of gamma radiation to small targets inside the brain. It does so by sending radiation beams through 201 holes in a device called a collimator helmet. Only at the point where all 201 beams converge at a single, finely focused point is enough radiation delivered to treat the diseased tissue while nearby healthy tissue is spared.Related Questions
