Abstract BACKGROUND Treatment of several spine disorders requires placement of pedicle screws. Detailed 3-dimensional (3D) anatomic information facilitates this process and improves accuracy. OBJECTIVE To present a workflow for a novel augmented-reality-based surgical navigation (ARSN) system installed in a hybrid operating room for anatomy visualization and instrument guidance during pedicle screw placement. METHODS The workflow includes surgical exposure, imaging, automatic creation of a 3D model, and pedicle screw path planning for instrument guidance during surgery as well as the actual screw placement, spinal fixation, and wound closure and intraoperative verification of the treatment results. Special focus was given to process integration and minimization of overhead time. Efforts were made to manage staff radiation exposure avoiding the need for lead aprons. Time was kept throughout the procedure and subdivided to reflect key steps. The navigation workflow was validated in a trial with 20 cases requiring pedicle screw placement (13/20 scoliosis). RESULTS Navigated interventions were performed with a median total time of 379 min per procedure (range 232-548 min for 4-24 implanted pedicle screws). The total procedure time was subdivided into surgical exposure (28%), cone beam computed tomography imaging and 3D segmentation (2%), software planning (6%), navigated surgery for screw placement (17%) and non-navigated instrumentation, wound closure, etc (47%). CONCLUSION Intraoperative imaging and preparation for surgical navigation totaled 8% of the surgical time. Consequently, ARSN can routinely be used to perform highly accurate surgery potentially decreasing the risk for complications and revision surgery while minimizing radiation exposure to the staff.

Abstract INTRODUCTION Minimally invasive surgery (MIS) is considered superior to open surgery because of the reduced recovery times, pain medication, and infection rates. However, the smaller surgical site increases the surgical difficulty as physical landmarks are no longer visible. Using an augmented reality (AR) overlay where a patient's CT or MRI information is registered to the physical patient, users would be able to view the internal patient anatomy while maintaining a small surgical site. Our goal is to determine how to best render the virtual information intuitively for surgeons while operating MIS cases. METHODS Given AR systems available today, there are many options regarding rendering virtual objects. Using the Microsoft HoloLens, we virtually overlay two layers of the patient body (soft and hard tissue) and vary the opacity and color in real time. Surgeons wore the headset during nonoperative stages of the surgery and asked usability questions regarding the system. RESULTS Users surveyed displayed strong predilection towards more opaque renderings of hard tissue, with an average setting of approximately 95%. Comparatively, users preferred much lower opacity for soft tissue, with an average opacity of 26.88%, and with some users wanting no visualization of soft tissue. It was also found that users at earlier stages in their training (ie, medical students and residents) preferred more contrasting colors, whereas attendings and fellows preferred grey-scaled color profiles analogous to traditional imaging modalities. CONCLUSION Based on the results found in the usability testing, it was found that current state-of-the-art AR headsets are not currently well suited for the operating room. Ergonomics, eye fatigue, and changing lighting conditions were all undesirable factors, especially for extended use during surgery. Data gathered from the rendering tests and pain points will be further addressed in the next generation of AR headsets.

AbstractAugmented reality (AR) superimposes computer-generated virtual objects onto the user’s view of the real world. Among medical disciplines, neurosurgery has long been at the forefront of image-guided surgery, and it continues to push the frontiers of AR technology in the operating room. In this systematic review, we explore the history of AR in neurosurgery and examine the literature on current neurosurgical applications of AR. Significant challenges to surgical AR exist, including compounded sources of registration error, impaired depth perception, visual and tactile temporal asynchrony, and operator inattentional blindness. Nevertheless, the ability to accurately display multiple three-dimensional datasets congruently over the area where they are most useful, coupled with future advances in imaging, registration, display technology, and robotic actuation, portend a promising role for AR in the neurosurgical operating room.

This paper describes the MAGI (microscope-assisted guided interventions) augmented-reality system, which allows surgeons to view virtual features segmented from preoperative radiological images accurately overlaid in stereo in the optical path of a surgical microscope. The aim of the system is to enable the surgeon to see in the correct 3-D position the structures that are beneath the physical surface. The technical challenges involved are calibration, segmentation, registration, tracking, and visualization. This paper details our solutions to these problems. As it is difficult to make reliable quantitative assessments of the accuracy of augmented-reality systems, results are presented from a numerical simulation, and these show that the system has a theoretical overlay accuracy of better than 1 mm at the focal plane of the microscope. Implementations of the system have been tested on volunteers, phantoms, and seven patients in the operating room. Observations are consistent with this accuracy prediction.

AbstractPatient tracking is an essential part in a surgical augmented reality system for correct hologram to patient registration. Augmented reality can support a surgeon with visual assistance to navigate more precisely during neurosurgical interventions. In this work, a system for patient tracking based on infrared markers is proposed. These markers are widely used in medical applications and meet the special medical requirements such as sterilizability. A tracking accuracy of 0.76 mm is achieved when using the near field reflectivity and depth sensor of the HoloLens. On the HoloLens a performance of 55–60 fps is reached, which grants a sufficiently stable placement of the holograms in the operating room.

Today, surgical operations are less invasive than they were a few decades ago and, in medicine, there is a growing trend towards precision surgery. Among many technological advancements, augmented reality (AR) can be a powerful tool for improving the surgery practice through its ability to superimpose the 3D geometrical information of the pre-planned operation over the surgical field as well as medical and instrumental information gathered from operating room equipment. AR is fundamental to reach new standards in maxillofacial surgery. The surgeons will be able to not shift their focus from the patients while looking to the monitors. Osteotomies will not require physical tools to be fixed on patient bones as guides to make resections. Handling grafts and 3D models directly in the operating room will permit a fine tuning of the procedure before harvesting the implant. This article aims to study the application of AR head-mounted displays (HMD) in three operative scenarios (oncological and reconstructive surgery, orthognathic surgery, and maxillofacial trauma surgery) by the means of quantitative logic using the Quality Function Deployment (QFD) tool to determine their requirements. The article provides an evaluation of the readiness degree of HMD currently on market and highlights the lacking features.

The medical community is constantly looking for technological solutions to reduce use-error and improve procedures to benefit the healthcare system worldwide. One area that has seen frequent improvement in the past few decades due to improved computing capabilities, lower cost and better displays has been augmented reality (AR) (Sauer, Khamene, Bascle, Vogt, & Rubino, 2002). In an operating room, surgeons and anesthesiologists are required to attend to a patient while receiving information from many different displays and instruments. This paper analyzes the human factors components of various AR devices and information display techniques to provide design guidelines for display configurations of wearable, medical AR devices that will improve upon current methods of information presentation in the operating room.
