Abstract
A surgical system includes an AR headset and a AR headset controller. The AR headset is configured to be worn by a user during a surgical procedure and has a see-through display screen configured to display an AR image and to allow at least a portion of a real-world scene to pass therethrough for viewing by the user. The AR headset also includes an opacity filter positioned between at least one of the user's eyes and the real-world scene when the see-through display screen is viewed by the user. The opacity filter provides opaqueness to light from the real-world scene. The AR headset controller communicates with a navigation controller to receive navigation information from the navigation controller which provides guidance to the user during the surgical procedure on an anatomical structure, and generates the AR image based on the navigation information for display on the see-through display screen.
