“…The surgeon needs to alternate between the macroscopic view of the surgical field and the endoscopic view. AR navigation has recently been employed during brain, spinal, plastic, maxillofacial, and several other highly technically demanding surgeries [6][7][8] . However, few studies have focused on its use in upper limb arthroscopy 9 .…”

Background: The purpose of this study was to develop and evaluate a novel elbow arthroscopy system with superimposed bone and nerve visualization based on preoperative computed tomography (CT) and magnetic resonance imaging (MRI) data. Methods: We obtained bone and nerve segmentation data by CT and MRI, respectively, of the elbow of a healthy human volunteer and cadaveric Japanese monkey. A life size 3-dimensional (3D) model of human organs and frame was constructed using a stereo-lithographic 3D printer. Elbow arthroscopy was performed using the elbow of a cadaveric Japanese monkey. The augmented reality (AR) range of error was examined at 1 cm and 2 cm scope–object distances. Results: We successfully performed AR arthroscopy using the life-size 3D elbow model and the elbow of the cadaveric Japanese monkey by making anteromedial and posterior portals. The computer graphics (CG) position and shape were initially different because of lens distortion. The CG position and shape were corrected to match the arthroscopic view using lens distortion parameter estimates based on the calibration pattern. AR position and shape errors were 2.3 mm at 1 cm scope–object distance and 3.6 mm at 2 cm scope–object distance. Conclusion: We attained reasonable accuracy and demonstrated the working of the designed system. Given the multiple applications of AR-enhanced arthroscopic visualization, it has the potential to be the next-generation technology for arthroscopy. This technique will contribute the reduction of serious complications associated with elbow arthroscopy.

“…The AR systems, in which patient-specific information generated from preoperative data is displayed intra-operatively, have been clinically applied in a range of surgical fields to enhance accuracy, safety and efficiency during surgery (Okamoto et al, 2015). Kersten-Oertel et al (2015) developed an AR system for neurovascular surgery to visualize internal anatomical structures such as blood vessels during surgery. It merges volume-rendered vessels with the live view of the patient in the operating room.…”

The use of Augmented Reality (AR) for visualising blood vessels in surgery is still at the experimental stage and has not been implemented due to limitations in terms of accuracy and processing time. The AR also hasn't applied in breast surgeries yet. As there is a need for a plastic surgeon to see the blood vessels before he cuts the breast and before putting the implant, this paper aims to improve the accuracy of augmented videos in visualising blood vessels during Breast Implant Surgery. The proposed system consists of a Weighted Integral Energy Functional (WIFE) algorithm to increase the accuracy of the augmented view in visualising the occluded blood vessels that covered by fat in the operating room. The results on breast area shows that the proposed algorithm improves video accuracy in terms of registration error to 0.32 mm and processing time to 23 sec compared to the state-of-the-art method. The proposed system focuses on increasing the accuracy in augmented view in visualising blood vessels during Breast Implant Surgery as it reduces the registration error. Thus, this study concentrates on looking at the feasibility of the use of Augmented Reality technology in Breast Augmentation surgeries.

“…Third, a key challenge is acceptance of the HMD into the radiology reading room. There has been extensive research into the augmented reality in surgery [39][40][41] and experience has dictated that bulky HMDs will not be accepted into the operating room by surgeons [42].…”

Abstract:In recent years, advances in medical imaging have provided opportunities for enhanced diagnosis and characterization of diseases including cancer. The improved spatial resolution provides outstanding detail of intricate anatomical structures, but has challenged physicians on how to effectively and efficiently review the extremely large datasets of over 1000 images. Standard volume rendering attempts to tackle this problem as it provides a display of 3D information on a flat 2D screen, but it lacks depth perception and has poor human-machine interface (HMI). Most recently, Augmented Reality/Virtual Reality (AR/VR) with depth 3-dimensional (D3D) imaging provides depth perception through binocular vision, head tracking for improved HMI and other key AR features. In this article, we will discuss current and future medical applications of AR including assessing breast cancer. We contend that leveraging AR technology may enhance diagnosis, save cost and improve patient care.

Augmented reality in neurovascular surgery: feasibility and first uses in the operating room

Abstract: Augmented reality is a promising technology for neurovascular surgery. However, for more complex anomalies such as AVMs and AVFs, better visualization techniques that allow one to distinguish between arteries and veins and determine the absolute depth of a vessel of interest are needed.
