Item NextMed, Augmented and Virtual Reality platform for 3D medical imaging visualization(ACM, 2019-10-16) González-Izard, S.; Alonso Plaza, Ó´; Sánchez Torres, R.; Juanes-Méndez, J. A.; García-Peñalvo, F. J.The visualization of the radiological results with more advanced techniques than the current ones, such as Augmented Reality and Virtual Reality technologies, represent a great advance for medical professionals, by eliminating their imagination capacity as an indispensable requirement for the understanding of medical images. The problem is that for its application it is necessary to segment the anatomical areas of interest, and this currently involves the intervention of the human being. The Nextmed project is presented as a complete solution that includes DICOM images import, automatic segmentation of certain anatomical structures, 3D mesh generation of the segmented area, visualization engine with Augmented Reality and Virtual Reality, all thanks to different software platforms that have been implemented and detailed, including results obtained from real patients. We will focus on the visualization platform using both Augmented and Virtual Reality technologies to allow medical professionals to work with 3d model representation of medical images in a different way taking advantage of new technologies.Item 360º vision applications for medical training(ACM, 2017-10-18) González Izard, S.; Juanes Méndez, J. A.; García-Peñalvo, F. J.; Jiménez López, M.; Pastor Vázquez, F.; Ruisoto, P.In recent years, 360º videos combined with virtual reality (VR) techniques have been developed so that users can experience the content and interact with the environment, rather than just watch them. These technological resources offer an immersive vision in which each person can choose where to look at. Therefore, we began to move away from the classic forms of traditional recording and reproduction to focus on the most innovative production and video viewing in 360 degrees as a more real-world technology experience that allows the visualization of panoramic images in 360º, which facilitates a complete perspective of an object or environment with a surprising luxury of details, through images captured from different angles. We present a teaching experience of 360 degree immersive visualization of an operating room and an anatomical dissection room, with the aim of generating a virtual environment for learning, training and valuing the equipment that exists in these medical rooms.Item Virtual Simulation for Scoliosis Surgery(ACM, 2017-10-18) González Izard, S.; Juanes Méndez, J. A.; Gonçalvez Estella, J. M.; Sánchez Ledesma, M. J.; García-Peñalvo, F. J.; Ruisoto, P.Virtual Reality is currently one of the most emerging innovative technologies, and over the last year we have seen how different sectors have successfully applied it ranging from the most industrial sectors to the education or medical sectors. The system presented in this article consists on a virtual simulation of a lumbar transpedicular fixation surgical operation, in order to achieve a fixation of three vertebral functional units. The user will be inside an operating room, in front of the patient, which in this case is a complete 3D model that includes musculature, complete skeleton, ligaments, veins, arteries ... The actions to be performed include selecting the right tool and subsequently its use, so that the user interacts with the system by moving his hands. The objective of this study is for the user to know the tools that should be used in this procedure and the steps that must be followed. In addition, virtual simulation merges with videos of real surgery, making this system a great tool for training in this type of surgery, demonstrating the potential of Virtual Reality as a useful technology for training. This system includes a theoretical part that shows all the steps and all the information to the user, and a practical part, in which you must interact with the system to perform each step of the procedure itself. This interactive virtual simulation has been developed by the company specialized in advanced systems of Augmented Reality and Virtual Reality ARSOFT, in collaboration with members of the Research Groups of the University of Salamanca VisualMed Systems and GRIAL.
