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 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 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 invention relates to a medical display (10) comprising a position determination system for ascertaining the position of at least one pointer (1) which is pointing onto the display surface (7) of the display (10), wherein the position determination system uses mufti-layered pointing position determination, wherein position-determining layers (A, B) each ascertain a two-dimensional pointing intersection (5, 6), and wherein said layers (A, B) are spaced from each other and arranged one above the other in relation to the display surface.
