Obtaining adequate and precise anatomical information is mandatory to prevent vascular access–related complications in dialysis patients. For this purpose, we underwent Doppler ultrasound, vascular access angiogram, and plain computer-assisted tomography scan of the arm with vascular access. With the use of computer graphics software, the anatomical structure of the vascular access can be visualized three dimensionally which is shared among the staffs for precise and better recognition. Furthermore, created object is applicable for virtual reality and/or augmented reality presentation that provides useful means for education and practical procedures in the management of vascular access.

Preoperative Plan

Computer Aided Surgery (CAS) is helpful, but it clutters an already overcrowded operating theatre, and tends to disrupt the workflow of conventional surgery. In order to provide seamless computer assistance with improved immersion and a more natural surgical workflow, we propose an augmented-reality based navigation system for CAS. Here, we choose to focus on the proximal femoral anatomy, which we register to a plan by processing depth information of the surgical site captured by a commercial depth camera. Intra-operative three-dimensional surgical guidance is then provided to the surgeon through a commercial augmented reality headset, to drill a pilot hole in the femoral head, so that the user can perform the operation without additional physical guides. The user can interact intuitively with the system by simple gestures and voice commands, resulting in a more natural workflow. To assess the surgical accuracy of the proposed setup, 30 experiments of pilot hole drilling were performed on femur phantoms. The position and the orientation of the drilled guide holes were measured and compared with the preoperative plan, and the mean errors were within 2mm and 2°, results which are in line with commercial computer assisted orthopedic systems today.

This article is devoted to the issues of visualization and information processing, in particular, improving the visualization of three-dimensional objects using augmented reality and virtual reality technologies. The globalization of virtual reality has led to the introduction of a new term "augmented reality"into scientific circulation. If the current technologies of user interfaces are focused mainly on the interaction of a person and a computer, then augmented reality with the help of computer technologies offers improving the interface of a person and the real world around them. Computer graphics are perceived by the system in the synthesized image in connection with the reproduction of monocular observation conditions, increasing the image volume, spatial arrangement of objects in a linear perspective, obstructing one object to another, changing the nature of shadows and tones in the image field. The experience of observation is of great importance for the perception of volume and space, so that the user "completes" the volume structure of the observed representation. Thus, the visualization offered by augmented reality in a real environment familiar to the user contributes to a better perception of three-dimensional object.

Through virtual interaction and multivariate communication, the social interaction and life satisfaction of elderly people can be improved. This study integrated virtual reality (VR) and augmented reality (AR) to construct a visualized reminiscence therapy system, which provides not only reminiscence entertainment but may also aid in dementia prevention for healthy and sub-healthy (a therapeutic working concept which defines an intermediate stage between health and disease) elderly people. Images taken by an LG 360 CAM are primarily introduced into Power Director 360 as the guide interface. The special effects are joined using After Effects. With the model constructed under 3ds Max, the reminiscence therapy system integrated by virtual reality and augmented reality is then established by the Unity engine. It is shown that the developed 3D ancient building model can be used by Samsung Note 5 smartphones as well as VR CASE glasses to increase the immersive experience for the elderly. Through nostalgic elements triggered by the AR/VR three-dimensional model and video/audio interaction, the feasibility of our integrated system for reminiscence therapy is thus verified. Through reminiscence therapy, memories and thoughts can fully be activated as a therapy for elderly people. The visualized reality system developed in this study can further promote the social interactional satisfaction of elderly people.

Abstract The quality of welded joints depends on many factors. The relevant standards stipulate technical conditions of welds quality assessment, which provides the basis for stating whether the given joint is compatible with the requirements or whether it is defective. In practice, making welded joints that are totally devoid of defects is extremely difficult. To conduct the control of inner structure of the given joint a non-destructive method with the application of industrial CT scanner might be applied. This modern diagnosing method combines the x-ray examination with advanced computer technology. The basic advantage of computer-assisted tomography consists in examining objects in three dimensions and the possibility to carry out three-dimensional reconstructions. The aim of this article is to discuss the use of this method to evaluate the quality of welded joints made of aluminium alloys. Capabilities of computer-assisted tomography were depicted by the case of weld probes constructed with TIG (ang. Tungsten Inert Gas) welding by different process variables. One has made the analysis of the quality of probes showing the smallest and the biggest internal and external welding defects.

SummaryObjective: To describe the use of two- dimensional computer-assisted tomography (CT) with three-dimensional (3D) reconstruction in the diagnosis and planning of surgical treatment of a case of false ankylosis of the temporomandibular joint.Case report: A young European Shorthaired cat was presented with the complaint of inability to eat and open its jaws. A CT scan with 3D reconstruction allowed visualization of the lesion which was causing extra- articular ankylosis of the temporomandibular joint. Surgery was performed to resect an osseous lesion of the zygomatic arch, thus freeing the temporomandibular joint. Postoperative physical therapy was initiated immediately following surgery, and then carried out by the owner with a one year follow-up. Clinical examination of the cat was performed during regular office visits (at 1 month and 3 months following surgery), which allowed objective assessment of postoperative recuperation. At the end of a year, the owners reported that the cat had maintained sufficient jaw opening without any signs consistent with chronic pain.Conclusion: Computed tomography scan with 3D reconstruction allowed planning of the surgical correction of extra-articular ankylosis of the temporomandibular joint, and in this case condylectomy was avoided, since temporomandibular joint range-of-motion was maintained.

The concept of education for children is important. The aspects that must be considered are methods and learning media. In this research innovative and alternative learning media are made to understand fruits for children with Augmented Reality (AR). Augmented Reality (AR) in principle is a technology that is able to combine two-dimensional or three-dimensional virtual objects into a real environment and then project it. This learning media combines picture cards and virtual reality. Markers contained on picture cards will be captured by the mobile device camera, processed and will 3D animated pieces appear on the mobile screen in realtime. By using the concept of combining real world, real images on cards and virtual, applications can stimulate imagination and sense of desire in children and motivation to learn more and more. 3D fruit estimation created using the 3D Blender application and the Augmented Rea process lity is made using Unity and the Vuforia SDK library. The application of fruit recognition has been applied to several child respondents and has been tested on several types and brands of Android-based mobile phones. Based on research trials, 86% of 30 respondents stated that the application which was developed very effectively as a medium for the introduction of fruits.

The Metaverse is a pervasive expression of technological culture whose impact will be global. First, through knowledge, then through social, and now through geo-spatial, AI (the foundation of the Metaverse) will connect all entities on Earth through digital means thereby creating a three-dimensional informational and experiential layer across the world dubbed the Metaverse. The Metaverse has four characteristics: augmented reality, lifelogging, mirror worlds, and virtual reality. From the standpoint of Christian cultural engagement, a contextual theology has yet to be developed. In the work that follows, the Metaverse is engaged through a combination of contextualization and wholemaking from the standpoint of posthumanism and mysticism. The study focuses on evolutionary wholemaking as identified by Teilhard/Delio, while being guided by Bevans’ five (early) models of contextualization. The method of contextual wholemaking enables new ways of seeing, embracing, communing, complexifying, and creating within the four spheres of the Metaverse. After exploring the nature of the Metaverse in the first half of the paper, insights were gathered from the dialogue between contextual theology and culture and discussed in the second half of the paper.

Background: Current intracorporeal imaging technologies are not sufficient. Many research studies have developed ways to integrate alternate technologies into existing procedures. To understand the use of these different intracorporeal imaging technologies a systematic literature review was performed to formulate alternative technology-based medical device designs. Methods: Using the keywords of “Ultrasound Vascular Access” a total of 6,402 articles were found. Further refinement using “Intravenous, cannulation, augmented reality, virtual reality, mixed reality, and peripherally inserted catheters” narrowed the results to 200 articles. Results: Two major themes were identified: advanced intracorporeal imaging used during surgical procedures and those used only to acquire vascular access during a variety of simpler medical procedures (n=35). Conclusion: Based on these initial findings, integrated augmented reality system for ultrasound (mixed reality) appears to be the most promising technology that is effective, reduced cognitive workload and has adequate usability in clinical environments.
