Smartphone-assisted augmented reality technology for preoperative planning in spine surgery

Objective. To present a virtual three-dimensional model of pathologically altered segments of the patient’s spine and to analyze the results of its application when planning a surgical intervention in the smartphone-assisted augmented reality.Material and Methods. A three-dimensional modeling of the target area of the intended surgical site was performed based on computed tomography data of five patients with various spinal deformities. A smartphone application has been developed that allows displaying a three-dimensional object of the intended surgical site in the form of augmented reality.Results. The created virtual three-dimensional models were successfully used in five cases for preoperative planning and simulation training before surgery, which allowed to see in detail the anatomical features of the spine, the location of vascular structures when contrasting them, and to plan the direction of the screws. The potential of using augmented reality in clinical practice was demonstrated.Conclusion. The advantages of the smartphone-assisted augmented reality technology for preoperative planning in spine surgery are the simplicity of creating a computer model, the possibility for a surgeon to use a three-dimensional model for orientation in complex anatomical zone at any time of surgery, and the reduction in the risk of technical errors.

Augmented Reality Technology

It is common occurrence that on-site workers misunderstand various detailing aspects of the provided documentation. Some of them can be unclear and should be discussed again due to construction related processes. In order to deal with this issue the application for mobile devices was proposed. The developed application allows to visualize two-dimensional print projects with the help of VR/AR (Virtual Reality/Augmented Reality) technology. The paper is focused on the assessment of the possibility to use the VR/AR technology during the process of construction. The feasibility of the solution is tested on the basis of a three-dimensional model created with the software operating in accordance with Building Information Modeling (BIM) technology. The developed mobile VR/AR solution was enhanced with basic functionality to verify structural members as well as entire structural system. Moreover, it allows to communicate in a simple manner, which can lead to the improving of the effectiveness and preventing the risk of construction errors.

Campus Building

STMIK Umel Mandiri as one of the universities in Jayapura is still less well known, apart from being relatively new in its age and the location of the campus building which is blocked by buildings. So that people sometimes do not know the exact location of the campus. To promote the campus, one of the advertising media used is brochures. Along with current technological developments, augmented reality technology has emerged which is able to combine 2 (two) realities, namely the real and virtual world. When used in brochures, it can provide a feel and experience for readers. So that promoting goods or services can be done more interactively, as well as providing more information to consumers about the product. This augmented reality technology is then used as a solution to the problems faced by STMIK Umel Mandiri in promoting its educational institutions. The purpose of this research is to produce an android application that can display a 3 (three) dimensional brochure model by utilizing augmented reality technology so that it can help the public to get to know the campus to be chosen well. The research method has several stages, namely collecting data about the needs of prospective new students regarding information about the STMIK Umel Mandiri campus, then making a 3 (three) dimensional model of the STMIK Umel Mandiri Campus Building. Then next, do the design of compatible augmented reality on smartphone devices using the Android operating system, and produce 3 (three) dimensional augmented reality objects. This research produces an application based on augmented reality technology that is used to help promote the STMIK Umel Mandiri Campus through devices with the android operating system.

The One

Gravity survey has been carried out around central part of Mashiki, Kumamoto, Japan, where was severely damaged by 2016 Kumamoto earthquake. Dense observations were performed at more than 450 sites around the central part of Mashiki. The observation sites satisfy enough density to discuss density structure shallower than 500-meter depth around the target area. After applying some corrections to the observed data, Bouguer anomaly is obtained and three dimensional model of gravity basement is estimated. As a result, a graben runs parallel to the Akitsukawa River and some isolated small basins are found inside of the graben. The central part of Mashiki is located immediately above of the one of such the small basins. We also analyze focusing and defocusing effects of ray of seismic wave under very simple assumptions and it is found that the central part of Mashiki locates close to a focusing area.

Do So

In this study we wanted to analyse how additive manufacturing could bring benefit to the treatment of intracranial aneurysms. To be able to do so we segmented Magnetic Resonance Imaging (MRI) images, specifically we used images from a Time-Of-Flight (TOF) 3D sequence. Once we obtained the virtual three-dimensional model from the diagnostic images, we proceeded to create a physical model through 3D-printing that was later used by the surgeon for a preoperative planning.
