Abstract
In a method and apparatus for calibrating a navigation system in relation to image data of a magnetic resonance apparatus, positions of at least three markers arranged in an imaging volume of a magnetic resonance apparatus are determined with the navigation system in a first coordinate system, and are determined by means of magnetic resonance in a second coordinate system. From the positions of the markers in the two coordinate systems, a position and an orientation of the two coordinate systems to one another are determined. Localization data are transformed into the second coordinate system. An apparatus for conducting the method has at least one marker having a substance that can be detected using magnetic resonance technology, in spatial allocation to optical markings. A pickup coil can be spatially allocated to each marker.
