    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: 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.

    IPC: A61B34/20 ,  A61B90/00

    Abstract: A system and method for determining the spatial position and the shape of a surgical instrument (1) having a deformable body (2) by: providing an elasticity model of the surgical instrument (1); defining at least one parameter which influences the shape of the instrument (1); determining the spatial position and/or orientation of at least one tracking sensor (3) of the surgical instrument (1); determining the value of the at least one parameter; calculating the position and/or orientation of at least one part of the surgical instrument (1) with the aid of the elasticity model together with the determined value of the at least one parameter and the determined spatial position and/or orientation of the at least one tracking sensor (3). The present invention also relates to a surgical instrument (1) having a deformable body (2) comprising at least two sensors (3, 4), wherein at least one sensor is a tracking sensor (3) and at least one other sensor is a sensor (4) which allows the value of a predetermined parameter influences the shape of the instrument (1) to be determined.

    Abstract: A data processing method for generating a compensation information for hacking or for determining the position and/or orientation of an object in space, the method comprising the following steps performed by a computer: a) acquiring a predetermined constraint information defining one or more relative or absolute positions and/or orientations of the object in space; b) acquiring position and/or orientation data of the object while the object is positioned or moved while fulfilling the predetermined constraint; and c) determining the compensation information based on the predetermined constraint information and the acquired position and/or orientation data of the object.
