    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: A computer implemented method and a system for registering and tracking an anatomical structure of a patient. A method includes acquiring a first stereoscopic image dataset including video images having different viewing angles, and providing a first image content showing the anatomical structure; registering the first image dataset to a 3D image dataset showing the anatomical structure; acquiring a second stereoscopic image dataset comprising video images having different viewing angles and providing a second image content showing the anatomical structure, which differs from the first image content; and tracking the anatomical structure based on the second image dataset.

    Abstract: The present application relates to an optical observation device which is controlled in a sterility preserving manner, and to a corresponding controlling program and/or program storage medium. The optical observation device includes a main structure having at least one optical camera, a motorized support for positioning the main structure, and a control unit that receives a sequence of images from the at least one optical camera, searches a current image from the sequence of images for a trackable object, tracks the trackable object shown in the sequence of images subsequent to the current image, and controls the motorized support structure.

    Abstract: This document relates to technologies of determining a configuration of a medical imaging system comprising an x-ray source and an x-ray detector mounted on a gantry and an x-ray source collimator for shaping the x-ray beam emitted by the x-ray source, wherein at least one of the x-ray source and the x-ray detector is movable along the gantry. The configuration of the medical imaging system comprises the position of the x-ray source, the position of the x-ray detector and the settings of the x-ray source collimator and is to be used for capturing a marker image, wherein the position of the marker device can be calculated using the marker image.

    Abstract: Disclosed is a computer-implemented method of determining a spatial relationship between planning image data and current surface data which leads to improved surface registration accuracy by considering the elasticity and deformability of the tissue. The knowledge about the tissue can be estimated based on type of tissue and atlas information. For the process of generating surface registration points on specific anatomical regions, e.g. the face or forehead, are acquired with a classical navigated pointer or laser pointer. It is also possible to acquire points with surface scanners. Confidence values defining a probability for certain parts of the surface registration points being deformed in comparison to a planning image are read from atlas data and used to compensate for the deformation in the registration between the surface registration points and the planning image in order to render the registration valid.
