Claim 8:
9. A system for determining a 3D representation and localization of an object in an X-ray projection image with respect to a coordinate system, the system comprising a processing unit configured to execute a computer program product including sets of instructions causing the system to perform the following method:
receiving a first X-ray projection image,
classifying a first object in the first X-ray projection image,
receiving a first model of the first object,
determining at least a first partial representation of the first object and a first localization of the first object relative to a coordinate system, by applying the first model to match the first object in the first X-ray image,
receiving a second X-ray projection image,
classifying a second object in the second X-ray projection image,
receiving a second model of the second object,
determining at least a second partial representation of the second object and a second localization of the second object relative to the coordinate system, by applying the second model to match the second object in the second X-ray image,
determining a spatial arrangement of the second object relative to the first object;
classifying one further object in each received X-ray image, wherein different portions of that object extend into the received X-ray images, respectively, and
registering the X-ray images based on a known geometry of that object.
