About Leksell Gamma Knife Perfexion
Leksell Gamma Knife Perfexion maintains full clinical compatibility with the classic Leksell Gamma
Knife and is supported by efficacy and outcome data from over 500,000 treated patients worldwide
and thousands of peer-reviewed scientific articles, making it a proven choice for radiosurgery of
the brain. According to Elekta, Leksell Gamma Knife Perfexion reduces unwanted body dose to the
patient by up to 100 times compared with competing technologies, which is particularly important
for treatment of children and women of childbearing age, and allows for a dramatically increased
treatable volume, which is expected to increase the number of patients that can benefit from Gamma
Knife surgery. Elekta estimates that the fully automated and efficient single push-button approach
can save 3-5 working weeks of physician time per year at an average Gamma Knife center.
American Shared Hospital Services provides turnkey technology solutions for advanced radiosurgical
and radiation therapy services. AMS is the world leader in providing Gamma Knife radiosurgery
equipment, a non-invasive treatment for malignant and benign brain tumors, vascular malformations
