System and method for holographic image-guided non-vascular percutaneous procedures
Holographic image-guidance can be used to track an interventional device during a non-vascular percutaneous procedure. The holographic image guidance can be provided by a head-mounted device by transforming tracking data and body image data to a common coordinate system and creating a holographic display relative to a patient's body to track the interventional device during the non-vascular percutaneous procedure. The holographic display can also include graphics to provide guidance for the physical interventional device as it travels through the patient's anatomy.
