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.

Augmented reality patient positioning using an atlas

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.

Display screen or portion thereof with graphical user interface

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.

Optical tracking

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.

Generation of augmented reality image of a medical device

The present invention relates to a computer-implemented medical method of determining a spatial position of a medical optical observation device (), the method comprising executing, on a processor of a computer (), the steps of:&#x2014;acquiring position data describing, for a plurality of points in time, the spatial position of the observation device () within a co-ordinate system of a medical tracking system ();&#x2014;determining, based on the position data, average position data describing an average value for the position of the observation device () within the co-ordinate system of the medical tracking system ();&#x2014;acquiring image data describing a plurality of images acquired at the plurality of points in time via a camera () assigned to the observation device () and detecting the field of view () of the observation device ();&#x2014;determining, based on the image data, optical flow data describing an optical flow for the plurality of images;&#x2014;determining, based on the average position data and the optical flow data, focal plane position data describing a spatial position of the focal plane () of the observation device (). 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.

Microscope tracking based on video analysis

The invention is in particular directed to a data processing method for use in computer-assisted surgery, comprising the following steps: a) providing marker data which describe a spatial arrangement of at least one marker device and/or a change in a relative spatial arrangement of at least two marker devices (5, 6, 7); b) providing condition data which describe a condition for the spatial arrangement of at least one marker device and/or a condition for the change in the relative spatial arrangement of the at least two marker devices (5, 6, 7); and c) controlling a control flow of the data processing method on the basis of the marker data and the condition data.
