Three-dimensional image guided navigation by augmented reality

Augmented reality: 3D image-guided surgery

Background Over the last three decades, surgical practice has undergone a significant change with a move towards minimally invasive surgery (MIS) as the standard of care [1]. Although this has brought with it significant benefits, problems have also been associated with the advent of MIS. Perhaps the most substantial limitation associated with MIS is the loss of haptic feedback; this deficit is...

Augmented Reality and Wearable Technology in Image-guided Navigation and Preoperative Planning

A ugmented reality (AR) and wearable technology have many potential applications in health care. Upcom-ing technologies such as Microsoft HoloLens (Microsoft Corporation, Seattle, Wash.) and Oculus Rift (Oculus VR, Menlo Park, Calif.) are gaining popularity with the wider audience, but Google Glass (Google Inc., Mountain View, Calif.) is the prototype that has gained the most traction in plasti...

An augmented reality guidance probe and method for image-guided surgical navigation

This paper presents a novel Augmented Reality (AR) probe and method for use with image-guided surgical navigation systems. Its purpose is to enhance existing systems by providing a video image of the therapeutic site augmented with relevant structures preoperatively defined by the user. The AR probe consists of a video camera and a tracked reference plate mounted on a lightweight ergonomic casi...

Modeling Augmented Reality System, Image Guided Surgery Case Study

An Augmented Reality (AR) system supplements the real world with virtual (computer-generated) objects that appear to coexist in the same space as the real world. [2]. The main interactive characteristic that emerges from these systems is the user focus shared between real and virtual worlds. This limitation results in two different interfaces possibly inconsistent – one to deal with the physica...
