“…Since Thomas Caudell invented this concept in the early 1990s, 13 augmented reality has been applied to many domains. 14 In medicine, it is found in applications that use an optical device and/or a camera such as celioscopy, 4 arthroscopy, 15 endoscopy, 16,17 and microsurgery. 18 In each application, the purpose of augmented reality was to simplify and accelerate the access to complex data by associating them with the surgical field of view Most surgical navigation systems rely on optical or mechanical sensors, which are restricting and cumbersome for wrist arthroscopy, which is cluttered with many visual obstacles such as the patient's limb, the traction column, the surgeon's hands, and instruments.…”

One of the main problems in endoscopic surgery is positioning and placing both the optical device and the surgical instruments within the operative field. Triangulation of the instruments is only mastered after years of training. To smooth the learning curve, computer-assisted solutions have been developed in some disciplines such as in abdominal laparoscopy, 1 arthroscopy of the temporomandibular joint, 2 and hip arthroscopy. 3These computer-assisted endoscopic surgery systems require merging anatomical data and instrument positional data to enable the surgeons to orient themselves in a limited surgical field. 4 The anatomical data consist of a three-dimensional (3D) computed tomography (CT) or magnetic resonance imaging (MRI) reconstruction of the surgical field, whereas electromagnetic sensors provide data regarding the position of the instruments. In wrist arthroscopy, there is a long learning curve in mastering the position and placement of the arthroscope and instruments.5,6 To our knowledge, no computerassisted wrist arthroscopy system has been previously reported.The aim of this study was to develop and evaluate the feasibility of a computer-assisted system for arthroscopic surgery of the wrist. Keywords► arthroscopy ► augmented reality ► computer-guided surgery ► wrist AbstractPurpose In video surgery, and more specifically in arthroscopy, one of the major problems is positioning the camera and instruments within the anatomic environment. The concept of computer-guided video surgery has already been used in ear, nose, and throat (ENT), gynecology, and even in hip arthroscopy. These systems, however, rely on optical or mechanical sensors, which turn out to be restricting and cumbersome. The aim of our study was to develop and evaluate the accuracy of a navigation system based on electromagnetic sensors in video surgery. Methods We used an electromagnetic localization device (Aurora, Northern Digital Inc., Ontario, Canada) to track the movements in space of both the camera and the instruments. We have developed a dedicated application in the Python language, using the VTK library for the graphic display and the OpenCV library for camera calibration. Results A prototype has been designed and evaluated for wrist arthroscopy. It allows display of the theoretical position of instruments onto the arthroscopic view with useful accuracy. Discussion The augmented reality view represents valuable assistance when surgeons want to position the arthroscope or locate their instruments. It makes the maneuver more intuitive, increases comfort, saves time, and enhances concentration.

“…In laparoscopy, and generally in endoscopic surgery, the part of the environment where the surgeon's attention is focused during the surgical task (DVV's Perception Location [7]) is a stand-up monitor. Indeed, in such procedures, the surgeon operates watching endoscopic video images reproduced on the spatial display unit [8,9]. Therefore, the virtual information is usually merged with real-time video frames grabbed by the endoscope and presented on a stand-up monitor [10][11][12].…”

Robust and Accurate Algorithm for Wearable Stereoscopic Augmented Reality with Three Indistinguishable Markers

Abstract:In the context of surgical navigation systems based on augmented reality (AR), the key challenge is to ensure the highest degree of realism in merging computer-generated elements with live views of the surgical scene. This paper presents an algorithm suited for wearable stereoscopic augmented reality video see-through systems for use in a clinical scenario. A video-based tracking solution is proposed that relies on stereo localization of three monochromatic markers rigidly constrained to the scene. A PnP-based optimization step is introduced to refine separately the pose of the two cameras. Video-based tracking methods using monochromatic markers are robust to non-controllable and/or inconsistent lighting conditions. The two-stage camera pose estimation algorithm provides sub-pixel registration accuracy. From a technological and an ergonomic standpoint, the proposed approach represents an effective solution to the implementation of wearable AR-based surgical navigation systems wherever rigid anatomies are involved.

Abstract-The impressive development of medical imaging technology during the last decades provided physicians with an increasing amount of patient specific anatomical and functional data. In addition, the increasing use of non-ionizing real-time imaging, in particular ultrasound and optical imaging, during surgical procedures created the need for design and development of new visualization and display technology allowing physicians to take full advantage of rich sources of heterogeneous preoperative and intraoperative data. During 90's, medical augmented reality was proposed as a paradigm bringing new visualization and interaction solutions into perspective. This paper not only reviews the related literature but also establishes the relationship between subsets of this body of work in medical augmented reality. It finally discusses the remaining challenges for this young and active multidisciplinary research community.
