Abstract
In a method for determining a coordinate transformation between a coordinate system of a first object to be imaged by an X-ray apparatus and a coordinate system of a second object to be navigated relative to a first object, a transformation relationship is determined between a coordinate system of a position-acquisition system and the coordinate system of the first object by an offline calibration run, the position of the X-ray arm is determined while recording X-ray images of the first object, and the position of the second object is determined using the position-acquisition system.
