The present invention relates to a method for determining the spatial position of objects, in particular medical objects. First position data is acquired that describes a spatial position of an object in a first coordinate system. First transformation data is acquired that transforms the object's position from the first coordinate system to a second coordinate system. Based on the foregoing data, second position data is acquired that specifies the spatial position of the object in the second coordinate system. Second transformation data is acquired that transforms the object's position from the second coordinate system to an inertial coordinate system. Based on the second position data and the second transformation data, inertial position data is determined that specifies a position of the object in the inertial coordinate system.

Method for determining the spatial position of objects

The invention relates to a surgical instrument comprising a handle portion or mounting portion and a functional portion and/or tip, wherein a display device is provided on the instrument and includes or enables displays which serve to assist in image-guided and/or navigation-assisted surgery. It also relates to a method for navigating a surgical instrument, wherein its position is determined and tracked by means of a medical tracking system and the position data is processed within the framework of medical navigation by means of a medical navigation system, wherein displays for navigation assistance and/or for assisting in image-guided surgery are provided on the instrument or on an element which is positionally assigned to the instrument or fastened to the instrument.

Integration of surgical instrument and display device for assisting in image-guided surgery

The invention relates to a medical navigation marker device () comprising a light reflector, characterised in that the reflector features a marker pattern () having the following features:&#x2014;the marker pattern () points in more than one spatial direction; &#x2014;the marker pattern () comprises at least one moire pattern () which points in more than one spatial direction; and&#x2014;the marker pattern () comprises a face identification pattern () which identifies the face of the marker being viewed from a particular spatial direction. The invention also relates to a combination of a medical marker device () and a medical navigation system () which uses the marker device () as a spatial position and/or orientation marker, and to the use of a medical marker device () for providing guidance to a user of a medical navigation system () by evaluating the spatial position and/or orientation information provided by the marker device.
