Classification: CPC G  A | IPC A  G

Claim 0:
1. A method for determining a spatial arrangement of objects relative to each other based on X-ray projection images comprising the steps of:
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; and
determining a spatial arrangement of the second object relative to the first object;
wherein the method further comprises the steps of 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.
