Augmented reality isn’t just for catching Pokémon anymore. A new technology from Leica Microsystems uses “image injection” to display virtual overlays within a surgical microscope to help guide a neurosurgeon’s hands. It was recently used by Dr. Joshua Bederson of Mount Sinai Health System in New York to treat a patient with an aneurysm.Bederson worked closely with Leica and Brainlab, the company that makes the software, to develop the tool. He is now using it all of his cases, according to a statement released by Mount Sinai. Called CaptiView, the system links image-guided surgery (IGS) software to the microscope hardware itself, laying down critical visual information (such as images from a brain scan) directly on top of a patient’s brain. Both two- and three-dimensional images can be injected.
