Architecture of a Hybrid Video/Optical See-through Head-Mounted Display-Based Augmented Reality Surgical Navigation Platform

In the context of image-guided surgery, augmented reality (AR) represents a ground-breaking enticing improvement, mostly when paired with wearability in case open surgery. Commercially available AR head-mounted displays (HMDs), designed for general purposes, are increasingly used outside their indications to develop surgical guidance applications ambition demonstrate potential The proposed literature underline hunger AR-guidance room together limitations that hinder commercial HMDs from being answer such need. medical domain demands specifically developed devices address, ergonomics, achievement accuracy objectives and compliance device regulations. framework an EU Horizon2020 project, hybrid video optical see-through headset software architecture, both be seamlessly integrated into workflow, has been developed. this paper, overall architecture system is described. HMD navigation platform was positively tested on seven patients aid surgeon while performing Le Fort 1 osteotomy cranio-maxillofacial demonstrating value approach safety usability platform.
