    Abstract: A medical tracking method for tracking a spatial position of a medical instrument within a medical workspace including an anatomical structure of a patient. The method includes: acquiring, using a first camera targeted on the medical workspace, instrument position data describing a spatial position of the medical instrument with respect to a first camera; acquiring, using a second camera and at least one optical tracking marker that is adapted to be recognized by the second camera, camera position data describing a spatial position of the first camera with respect to the anatomical structure, determining, based on the instrument position data and the camera position data, tracking data describing the spatial position of the medical instrument with respect to the anatomical structure; and tracking the spatial position of the medical instrument within the medical workspace using the tracking data.

    Abstract: The disclosed method encompasses using an augmented reality device to blend in augmentation information including for example atlas information. The atlas information may be display separately from or in addition to a patient image (planning image). In order to display the atlas information in a proper position relative to the patient image, the two data sets are registered to one another. This registration can serve for generating a diversity of atlas-based image supplements, for example alternatively or additionally to the foregoing for displaying a segmentation of the patient image in the augmented reality image. The disclosed method is usable in a medical environment such as for surgery or radiotherapy.

    Abstract: This document relates to a medical application of augmented reality in which areal image shows a medical device, or at least a part thereof. In an exemplary application, the real image further shows at least a part of a patient's body which is (to be) treated using the medical device. A part of the medical device might not be visible in the real image, for example because it extends into or behind the patient's body. In this case, the virtual image can comprise an augmentation of the medical device, which, for example, represents at least the part of the medical device which is invisible in the real image. This document in particular addresses a correct alignment of the augmentation with the medical device.

    Abstract: The present invention relates to a computer-implemented medical method of determining a spatial position of a medical optical observation device (1), the method comprising executing, on a processor of a computer (2), the steps of:—acquiring position data describing, for a plurality of points in time, the spatial position of the observation device (1) within a co-ordinate system of a medical tracking system (3);—determining, based on the position data, average position data describing an average value for the position of the observation device (1) within the co-ordinate system of the medical tracking system (2);—acquiring image data describing a plurality of images acquired at the plurality of points in time via a camera (4) assigned to the observation device (1) and detecting the field of view (5) of the observation device (1);—determining, based on the image data, optical flow data describing an optical flow for the plurality of images;—determining, based on the average position data and the optical flow data, focal plane position data describing a spatial position of the focal plane (6) of the observation device (1). The present invention further relates to a corresponding computer-program, a corresponding computer storage medium and a corresponding system for determining the spatial position of a medical optical observation device.
