Abstract

A method, a controller (26), and a surgical hybrid navigation system (10) for transferring a registration of three dimensional image data (43) of a surgical object (30) from a first to a second surgical navigation system (12, 14) are described. A first tracker (34) that is detectable by a first detector (16) of the first surgical navigation system (12) is arranged in a fixed spatial relationship with the surgical object (30) and a second tracker (36) that is detectable by a second detector (23) of the second surgical navigation system (14) is arranged in a fixed spatial relationship with the surgical object (30). The method comprises registering the three dimensional image data (43) of the surgical object (30) in a first coordinate system (20) of the first surgical navigation system (12) and determining a first position and orientation of the first tracker (34) in the first coordinate system (20) and a second position and orientation of the second tracker (36) in a second coordinate system (24) of the second surgical navigation system (14). The method further comprises determining a third position and orientation of the second coordinate system (24) in the first coordinate system (20) and registering the three dimensional image data (43) of the surgical object (30) in the second coordinate system (24) on the basis of the determined first, second and third positions and orientations.
