Method for registering an x-ray image data set with a navigation system, computer program product, and system

Abstract

The disclosure relates to methods, systems, and computer program products for registering a set of X-ray images with a navigation system. In the method, by a camera, at least one image of a reference object 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 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 as reference.
