Gamma Knife Perfexion, Developed for Power and Accuracy
Unlike other radiosurgical tools, the Gamma Knife was specifically designed to treat lesions in the brain, optimizing safety, efficiency and precision.
The latest generation Gamma Knife PERFEXION incorporates new technology, refining this powerful procedure while expanding its ability to map the radiation dose accurately. In addition, there has been a considerable increase in the number of conditions the Gamma Knife can treat effectively.
The treatment team combines the power of computers and diagnostic imaging with the Gamma Knife's preoperative planning and three-dimensional reference systems to create a detailed map of the pathological area. After a local anesthetic is applied, a frame is affixed to the patient's head.
Patients are comfortable with PERFEXION's small, light head frame. They rest quietly, as the system adjusts to fit the size and shape of the treatment area. Then, hundreds of cobalt-60 gamma ray beams are shot through the system's portals, converging on the target with a high level of accuracy.

About Washington hospital
Washington Hospital, located in Fremont, California, was the first hospital in the United States to treat patients using the new Leksell Gamma Knife Perfexion™, a revolutionary alternative to traditional open-brain surgery and/or daily radiation treatments, which are administered from four to six weeks. The Gamma Knife Perfexion instead uses focused doses of radiation without making a single incision to treat malignant and benign brain tumors in a matter of hours.
Washington Hospital's Gamma Knife® Program is led by one of the most accomplished teams of specialized physicians, physicists and nurses. Medical Directors neurosurgeon Sandeep Kunwar, MD, and radiation oncologist David Larson, MD, PhD, are both nationally and internationally recognized for their expertise, innovation and leadership in the field of Gamma Knife radiosurgery. Both board certified physicians, together they have more than 23 years of experience performing thousands of successful procedures.
