MediSim: a prototype VR system for training medical first responders
2002
This paper presents a prototype virtual reality (VR) system for training medical first responders. The initial application is to battlefield medicine and focuses on the training of medical corpsmen and otherfront-line personnel who might be called upon to provide emergency triage on the battlefield. The system is built upon Sandia 's multiuser , distributed VR pla fomz and provides an interactive, immersive simulation capability. The user is represented by an Avatar and is able to manipulate his virtual instruments and carry out medical procedures. A dynamic casualty simulation provides realistic cues to the patient's condition (e.g. changing blood pressure and pulse) and responds to the actions of the trainee (e.g. a change in the color of a patient's skin may result from a check of the capillary refill rate.) The current casualty simulation is of an injury resulting in a tension pneumothorax. This casualty model was developed by the University of Pennsylvania and integrated into the Sandia.

Animations of Medical Training Scenarios in Immersive Virtual Environments
2011 Workshop on Digital Media and Digital Content Management, 2011
Medical training centers often provide various simulations for students and professionals. Their goal is not only to make trainees practice specific scenarios but also to help them effectively transfer the acquired skills to the real world. Having in mind that virtual environments have already been acknowledged for their potential to improve the medical training process, we propose an approach for rapid generation of animated medical scenarios, which can be used as an additional training tool that fits into the time frame of a semester training program.
Virtual reality for training medical skills
Virtual reality (VR) is becoming a serious candidate for a learning environment for complex skills like vascular interventions. The diagnostics, dimensioning and insertion of the endograft stent has been modelled as a decision-making process and now faces its implementation in a VR learning space. Beyond the topological and morphological aspects it is the orientation and navigation in earlier-performed successful interventions that offer the opportunity for a competence-based learning process before the candidate surgeon enters the clinical stage.
Medical Training Simulation in Virtual Reality
Proceedings of International Scientific Conference on Telecommunications, Computing and Control, 2021
Digital technologies have a significant impact on medical training. Growing popularity of virtual and augmented reality changes the trend into virtual simulators. We gave an overview of key market products in the field of medical simulators in order to define main aspects for development of our own system. These aspects are: open surgery, realistic visualization, and haptic feedback. We described in details each of them and how it was implemented in our system. For open surgery was used appendectomy as most common procedure of this type of the surgery. In order to achieve realistic visualization, we implemented three different approaches for creating realistic and accurate 3D models. For haptic feedback, we took Novint Falcon and enhanced it with our custom grip which provides additional degrees of freedom.
Virtual reality training for health-care professionals
CyberPsychology & …, 2003
Emerging changes in health-care delivery are having a significant impact on the structure of health-care professionals' education. Today it is recognized that medical knowledge doubles every 6-8 years, with new medical procedures emerging everyday. While the half-life of medical information is so short, the average physician practices 30 years and the average nurse 40 years. Continuing education thus represents an important challenge to face. Recent advances in educational technology are offering an increasing number of innovative learning tools. Among these, Virtual Reality represents a promising area with high potential of enhancing the training of health-care professionals. Virtual Reality Training can provide a rich, interactive, engaging educational context, thus supporting experiential learning-by-doing; it can, in fact, contribute to raise interest and motivation in trainees and to effectively support skills acquisition and transfer, since the learning process can be settled within an experiential framework. Current virtual training applications for health-care differ a lot as to both their technological/multimedia sophistication and to the types of skills trained, varying for example from telesurgical applications to interactive simulations of human body and brain, to virtual worlds for emergency training. Other interesting applications include the development of immersive 3D environments for training psychiatrists and psychologists in the treatment of mental disorders. This paper has the main aim of discussing the rationale and main benefits for the use of virtual reality in health-care education and training. Significant research and projects carried out in this field will also be presented, followed by discussion on key issues concerning current limitations and future development directions.
Application of VR Technology to the Training of Paramedics
Applied Sciences
The virtual world has long been a focus not only of the gaming sphere, but also of the manufacturing and educational industries. The virtual world and its technology have many advantages, the basic ones being, for example, the use of experiential learning, with which the human brain can remember some things better and faster. It was due to the advantages of virtual reality technology that we decided to create an educational system on safety and health at work, and we focused on the healthcare segment due to the COVID-19 pandemic. Thanks to the cooperation of a professional consortium, we created an educational system for safety and health at work and carried out several extensive laboratory measurements, the results of which we followed up in practical measurements with medical staff. The created system is inherently unique and applicable and can be used across several industries. The article presents three basic types of scenarios as well as an evaluation of satisfaction with the p...
VReanimate II: training first aid and reanimation in virtual reality
Journal of computers in education, 2018
First aid saves lives and reanimation is an important part of it. In order to be able to perform the correct steps in emergency situations, appropriate behaviors must be learned and trained by as many people as possible. Nevertheless, easily accessible training opportunities are quite rare. We therefore developed a virtual reality (VR) application, VReanimate, that teaches about aspects of first aid in a controlled digital environment. In the first part of this article, we describe related work and conceptual and implementation details of our approach, that is based on a non-verbal and situated training in authentic scenarios. In the second part of this article, we present an evaluation of the system, including results concerning its usability and effects on the knowledge gain of different users. Conducting a mixed-methods study, we were able to observe a significant improvement in regard to knowledge about correct procedures in emergency situations and could confirm our hypothesis, that a non-verbal and situated design can be helpful for this purpose.

This paper presents the design and implementation of a distributed virtual reality (VR) platform that was developed to support the training of multiple users who must perform complex tasks in which situation assessment and critical thinking are the primary components of success. The system is fully immersive and multimodal, and users are represented as tracked, full-body figures. The system supports the manipulation of virtual objects, allowing users to act upon the environment in a natural manner. The underlying intelligent simulation component creates an interactive, responsive world in which the consequences of such actions are presented within a realistic, time-critical scenario. The focus of this work has been on the training of medical emergency-response personnel. BioSimMER, an application of the system to training first responders to an act of bio-terrorism, has been implemented and is presented throughout the paper as a concrete example of how the underlying platform architecture supports complex training tasks. Finally, a preliminary field study was performed at the Texas Engineering Extension Service Fire Protection Training Division. The study focused on individual, rather than team, interaction with the system and was designed to gauge user acceptance of VR as a training tool. The results of this study are presented.
The application of virtual reality technology in medical education and training
Global Journal of Information Technology, 2018
The development of virtual reality (VR) technology has greatly changed various industries, and medicine field is not exceptional too. This paper briefly introduces application of VR from two aspects. The application in theoretical teaching is virtual anatomy and virtual human projects have been widely researched in various universities and institutions all over the world, which will give medical students a more realistic visual sense compared to the traditional teaching methods with 2-D diagrams. And VR surgical system plays an important role in clinical practice training, which provides surgeons a simulation environment with vivid visual, auditory, haptic senses, it will be an excellent substitute of cadaver because residents and interns can repeat all kinds of operations in the system without limits.
Using virtual reality for medical diagnosis, training and education
International Journal on Disability and Human Development, 2006
In this paper we present a number of the immersive VR applications that we have developed during the past 18 months as a means of practically demonstrating the modelling approaches previously reported. The paper discusses the usefulness of the different approaches in assisting medical practitioners to diagnose and track conditions which might lead to impairment or disability, and how they can be used to train medical students to recognise such conditions or to undertake associated medical procedures. Initial findings of a survey of undertaken with medical practitioners as to the effectiveness of VR and in particular immersive models as diagnostic and training aids are also presented.
