What Are The Results Of Gamma Knife Surgery?
Gamma Knife CenterThe majority of brain tumors selected for treatment will disappear or stop growing over time. After one year 40% of arteriovenous malformations are cured increasing to 80% two years after treatment. The risk of spontaneous bleeding during this time is not more than untreated malformations.

What Are The Advantages Of Gamma Knife Surgery?
Gamma Knife CenterGamma Knife surgery is different from conventional radiation therapy of the brain because it is only directed to the target and spares unnecessary treatment of adjacent, normal brain. It differs because only a one day treatment is required rather than many treatments over several weeks and can be repeated if needed. It can be used in conjunction with conventional surgery as a boost and can be used in previously inoperable cases.
Related QuestionsHow 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 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 QuestionsWhat is gamma?
Gamma FAQ - Frequently Asked Questions about GammaThe luminance generated by a physical device is generally not a linear function of the applied signal. A conventional CRT has a power-law response to voltage: luminance produced at the face of the display is approximately proportional to the applied voltage raised to the 2.5 power. The numerical value of the exponent of this power function is colloquially known as gamma. This nonlinearity must be compensated in order to achieve correct reproduction of luminance.
