- Extended reality in the operating room: robot-assisted orthopedics surgery with live and interactive streaming for medical studentsPublication . Magalhães, Renato; Veloso, Rita; Gomes, Paulo Veloso; Marques, António; Pereira, JavierTraditionally, medical education comprises both theoretical learning in classrooms and clinical training in hospitals where students can gain clinical experience. This is mostly done on face-to-face teaching models, focused on the educational philosophy of “see one, do one, teach one”, was the standard teaching methodology in medical education. Medical education is transforming thanks to medical schools adopting innovations to new clinicians, such as immersive prepare techniques (extended reality): virtual reality, augmented reality and virtual reality. Immersive learning technologies, such as extended reality, can provide an engaging and interactive platform to generate a stimulating learning environment and with the recent development and increased accessibility of immersive technologies, educators have the potential to make simulation-based training more effective. By using holographic devices, such as Microsoft HoloLens 2®, and 5G wireless communications we intent to explore the innovative experience of a robot-assisted orthopaedic surgery, where the procedures were transmitted live stream to Pregraduate Medical Students using the Microsoft Remote Assist®. In addition, students had the opportunity to interact directly from a classroom to the operating room, asking to the surgeon about the procedures performed during surgery and get involved in the surgery, even remotely. At the end, students completed a questionnaire to evaluate the experience and the preliminary results made possible to assess the effectiveness of this experience and identify areas for improvement for future surgery transmission, revolutionizing the teaching and practice of surgery.
- Extended reality tools for medical training and educationPublication . Magalhães, Renato; Veloso, Rita; Magalhães, Renato; da Silva Veloso, Rita SofiaThe integration of extended reality (XR) in medical education represents a cutting-edge approach to simulation-based training. This study critically assesses XR software for medical teaching, with a focus on compatibility, medical specialization, and licensing requirements. The findings highlight the significant use in anatomy (44%) and surgical applications (26%). Virtual and mixed reality are the dominant technologies in this field, with the U.S. accounting for 62% of the companies involved. Specifically, HoloAnatomy, tested on HoloLens 2 and evaluated by seven healthcare professionals using NASA-TLX, was deemed intuitive and effective, though high device costs limit broader adoption. In conclusion, XR technologies hold substantial potential for advancing medical education, but the cost barriers must be overcome to enable wider implementation.
- m-Health system for the self-management of patients with heart failurePublication . Silva, Patrícia; Gomes, Paulo Veloso; Condeço, Jorge; Marques, António; Curado, Henrique; Veloso, Rita; Pereira, JavierIncreasingly, the use of technology is emerging as a tool to support health care. The new information and telecommunications technologies have triggered a new paradigm in health: in access, availability and management of information. Telemonitoring interventions in patients with heart failure have been shown to be cost effective in reducing the rate of hospitalisations and mortality. The development of m-Health applications focused on the centralization of care in patients, considering the perspectives of different stakeholders, promises results not only in clinical (mortality and morbidity) but also in patient outcome reports (quality of life and self-care). This work presents an integrated information system for telemonitoring and self-management of patients with heart failure.
- Mixed reality in an operating room using hololens 2—The use of the remote assistance from manufacturers techinicians during the surgeriesPublication . Veloso, Rita; Magalhães, Renato; Marques, António; Gomes, Paulo Veloso; Pereira, JavierThe aim of this work is that the participants, using HoloLens 2 and Dynamics 365 Remote Assistance, can receive all the training and information necessary for the correct application of prosthesis and medical devices remotely, from a support center of the manufacturers, avoiding the displacement and presence of these technicians during surgeries. After implementing this method, an analysis will be made on its impact, avoiding displacement and the presence of technicians during surgery, in terms of increasing satisfaction and improving the experience of the participants, reduction of various risks (including the risk of infection) and on reduction of some economic and environmental costs.

Veloso, Rita; Magalhães, Renato; Lima, Ana; Gomes, Paulo Veloso; Marques, António; Pereira, JavierVirtual Reality, Augmented Reality and Mixed Reality all have useful applications in the field of medicine, but Mixed reality has great potential because it allows for interaction with both real and digital Objects. Based on a previous literature review, a preliminary Delphi study was performed to obtain the opinion of a panel of 22 experts from several hospitals on the use of Mixed Reality tools, such as the HoLoLens 2, in surgeries. After data collection, a consensus letter was signed. According to experts, the most useful areas are medical education and surgical planning.
- Mixed reality in surgery: Development of a mixed reality application for surgical trainingPublication . Lima, Ana Carolina; Vilaça, Adélio; Veloso, Rita; Marques, António; Pereira, Javier; Magalhaes, Renato; da Silva Veloso, Rita Sofia; Pereira da Silva Marques, António José; Magalhães, RenatoMixed reality (MR) technology combines the real and the virtual world in an innovative way, where the users can see and interact with both worlds at the same time, having several applications in surgical practice, planning, and training. A MR application was developed to be used in a head mounted display (Microsoft HoloLens 2) for surgical training of the anterior cruciate ligament reconstruction surgery, with the aim of indicating the position of the femoral tunnel. This application was tested by 11 surgeons of the Centro Hospitalar Universitário de Santo António, who have all completed the simulation successfully, with an average time of under a minute. These surgeons answered an inquiry of satisfaction, where they all highlighted the potential that MR has in surgical training.
- Mixed reality in the operating room: A systematic reviewPublication . Magalhães, Renato; Oliveira, Ana; Terroso, David; Vilaça, Adélio; Veloso, Rita; Marques, António; Pereira, Javier; Pereira da Silva Marques, António José; Magalhães, RenatoMixed Reality is a technology that has gained attention due to its unique capabilities for accessing and visualizing information, becoming a valuable tool for medicine, particularly for the operating room and surgical learning; A systematic review was conducted following the PRISMA guidelines to answer the research questions established using the PICO framework; Although implementation of Mixed Reality applications in the operations room presents some challenges, when used appropriately, it can yield remarkable results. It can make learning easier, flatten the learning curve for several procedures, and facilitate various aspects of the surgical processes; Technical complexity, equipment costs, and steep learning curves present significant obstacles to the widespread adoption of Mixed Reality and computer-assisted evaluation. The possibility of integration of distinct medical imaging modalities and innovative functionalities holds promise for clinical applications. However, it is important to consider issues related to usability, bias, and statistical analyses need consideration. Mixed Reality offers significant benefits, but there are still open challenges such as ergonomic issues, limited field of view, and battery autonomy that must be addressed to ensure widespread acceptance.
- Segmentation of the bone structure from MRI Knee Joint - A use casePublication . Silva, Vasco; Vilaça, Adélio; Veloso, Rita; Coelho, Luís; Magalhães, Renato; Magalhães, RenatoManual and automatic segmentation techniques can be applied to DICOM medical images from magnetic resonance imaging (MRI) to extract certain structures, such as soft tissues, but the precise extraction of bone structures may be limited. This study studies these types of knee bone tissue segmentation on MRI, to avoid the need to resort to computed tomography (CT) for obtaining the desired bone structures. Manual segmentation was done using ITK-Snap and automatic segmentation algorithms were applied in Python and the ITK library. As a result of this study, it was found that although manual segmentation allowed for precise and consistent identification of the femur, tibia, fibula, and patella, the automatic segmentation needed to achieve the same level of accuracy.
- Telemonitoring in heart failure patient managementPublication . Silva, Patrícia; Gomes, Paulo Veloso; Condeço, Jorge; Curado, Henrique; Veloso, RitaHeart failure is a highly prevalent clinical syndrome, associated with high costs to the national health system and with a negative impact on patients’ quality of life. In order to reduce mortality, the rate of hospitalisations and improve quality of life, the empowerment of the patient for self-care from self-monitoring of signs and symptoms, taking medication, education about the disease, is a pillar of the treatment so that they can recognise signs of exacerbation of the disease in time and resort to health services early. Mobile health apps (mHealthh) have shown promise as a tool to engage and promote patient self-care, decreasing mortality and hospitalisations. However, to improve outcomes, more robust studies are needed on the development of the applications with regard to their contents, functions and usability, so as to overcome the obstacles to their use and ensure greater evidence of the benefits of their use.
