Abstract

In a navigation system and method, sensors at location-invariant points are used to define a coordinate system serves for identifying the motion of an organ. An image of the organ can be registered in parallel therewith, by selection of a point whose path in the coordinate system is identified and displayed, for which purpose the image plane attitude is also identified and displayed by acquisition of a further sensor. Alternatively, a sensor can be attached to the organ, this position thereof being identified and the motion path being determined therefrom. A sensor located at an instrument is acquired in parallel therewith. The position of the instrument in the coordinate system is identified and displayed. The instrument can be manually or automatically moved.
