METHOD AND SYSTEM FOR REGISTERING X-RAY IMAGE DATA SET WITH NAVIGATION SYSTEM

The disclosure relates to a method and a system for registering an X-ray image data set with a navigation system. In addition, the invention relates to a corresponding computer program products (1,16). In the method, by a camera (13), at least one image of a reference object (12) is recorded and, on the basis thereof, a current posture of the reference object is determined. It is then checked whether this posture fulfils a specified criterion, which also on an arrangement of the reference object at least partially outside a planned reconstruction volume (11) of the X-ray device, predicts an expected successful registration. On non-fulfillment of the criterion, a signal for adaptation of a relative alignment between the X-ray device and the reference object is automatically output. On fulfillment of the criterion, the X-ray images of the reference object are recorded, the posture of the reference object is determined, and the registration is carried out using the determined postures asreference. 本发明涉及一种用于将X射线图
