Title
(EN) SYSTEM AND METHOD FOR AUGMENTED REALITY SPINE SURGERY
(FR) SYSTÈME ET PROCÉDÉ POUR CHIRURGIE DE LA COLONNE VERTÉBRALE EN RÉALITÉ AUGMENTÉE
Abstract
(EN) A system and method for providing an imaging system comprising an image generator and a MD6DM model, for creating a synchronized augmented reality view of a subject. In particular, the imaging system enables augmenting and overlaying the MD6DM model over top of a corresponding physical model. Moreover, the imaging system anchors the MD6DM model to the physical model and synchronizes the two, such that a new image is created and overplayed over top of the physical model according to movement around the model, such as using a physical probe. This is accomplished by streaming the image generator directly to an HMD, tracking a position and location of the HMD, and adjusting the image generator based on the tracked movement. Thus, a dependency is created between the virtual model and the physical model. Guides can be provided to the user to enable the user to simulate and practice placing a virtual accessory, such as a model of an implantable screw, into a desired location in the physical model.
(FR) Un système et un procédé pour fournir un système d'imagerie comprenant un générateur d'images et un modèle MD6DM, pour créer une vue de réalité augmentée synchronisée d'un sujet. En particulier, le système d'imagerie permet l'augmentation et la superposition du modèle MD6DM sur un modèle physique correspondant. De plus, le système d'imagerie ancre le modèle MD6DM au modèle physique et synchronise les deux, de telle sorte qu'une nouvelle image est créée et lue par-dessus le modèle physique selon un mouvement autour du modèle, par exemple à l'aide d'une sonde physique. Ceci est accompli par la diffusion en continu du générateur d'images directement sur un HMD, le suivi d'une position et d'un emplacement du HMD, et le réglage du générateur d'images sur la base du mouvement suivi. Ainsi, une dépendance est créée entre le modèle virtuel et le modèle physique. Des guides peuvent être fournis à l'utilisateur pour permettre à l'utilisateur de simuler et de pratiquer la mise en place d'un accessoire virtuel, tel qu'un modèle d'une vis implantable, dans un emplacement souhaité dans le modèle physique.
