Abstract
An augmented-reality navigation system is used to assist a practitioner during a surgical operation on an anatomical structure of interest of a patient. The operation is planned on a pre-operational medical image. The navigation system comprises a camera that is intended to be worn by the practitioner on his head, a display device for displaying, in real-time, the real images acquired by the camera and an augmented-reality content superposed on the real images, and a control unit connected to the camera and to the display device. The control unit is configured to generate a predictive model of the movement of a marker placed in proximity to the anatomical structure of interest on the basis of the movement followed by the marker during one or more respiratory cycles of the patient. The predictive model is used to determine an opportune moment to perform the surgical operation as planned on the pre-operational image, and/or to display in augmented reality a three-dimensional anatomical model of the anatomical structure of interest.
