The Gamma Knife experts at NewYork-Presbyterian and Weill Cornell Medicine were excited to get their hands on the new Gamma Knife® Icon™ last week. After a dramatic September delivery and a month of installation and equipment preparation, the day finally arrived: The team was allowed into the treatment room to unpack all the accessories and start running tests and simulations. From warming up the soft mesh masks to ensure a perfect fit, to using a volunteer stand-in to check patient comfort and safety, to checking the control room feed from the treatment room, the team ran through many of the steps used in a real procedure. There is more unpacking and organizing and testing to do before we welcome our first patients in a few weeks, but we are eager to get to work! Watch the slide show below to see our team putting the new Gamma Knife through its paces.

Unaware of its important role, the Gamma Knife "test head" awaits a trial run

Mesh masks are warmed before use to make them malleable and form-fitting
