Abstract: Disclosed is a computer-implemented method of registering a digital model of an anatomical body part corresponding to a patient body part. The method encompasses input, to an augmented reality viewing device, of data defining a digital model of an anatomical body part, for example of the spine. The model comprises at least one vertex which corresponds to a specific part of the anatomical body part. The specific part is for example a landmark which is easily identifiable for a user, such a specific vertebra which may be found by palpation. Based on a known orientation of the augmented reality viewing device relative to the anatomical body part, visual information is displayed on a viewing unit of the augmented reality viewing device. The visual information indicates the position of the vertex as an overlay on the position of the specific part of the anatomical body part in the field of view of the augmented reality viewing device.

Abstract: The present invention relates to a computer-implemented medical method, a computer program and a system for determining a reconstructed image augmentation of a field of view provided by an augmented reality device (3), wherein an image location and/or at least one image orientation of at least one two-dimensional reconstructed image (9, 10 10) within the field view depends on the spatial position of at least one object (8, 11, 12).

Abstract: Disclosed is an incision foil made of a sterile, thin adhesive plastic film with a defined pattern printed on it (e.g. a fine grid pattern) which can be stuck e.g. on a patient's skin surface and which marks the anatomical region of interest. Using a camera, images are acquired of the attached film and the deformation of the pattern is digitized. With a computer vision algorithm the surface of the patient, which corresponds to the surface of the film, is reconstructed from the detected pattern features in the images in comparison to the known original undeformed pattern. Disclosed is also a method for determining a geometry of the surface of the patient using the incision foil.

Abstract: Provided is a method that encompasses the determination of a virtual trajectory within a virtual representation of a patient's anatomy, wherein the trajectory is defined by a user's visual axis relative to the three-dimensional virtual representation of the patient's anatomy. The method includes acquiring image data which describes the three-dimensional virtual representation of the patient's body part, acquiring position data which describes a spatial position of a user's visual axis within a virtual-world co-ordinate system, determining visualization data based on the image data and the position data, and determining virtual-world trajectory data based on the position data.
