1. A system for navigation support, the system comprising:
a marker detecting arrangement configured to detect a current spatial location of a set of markers assigned to a subject;
a processor is configured to:
receive a plurality of 2D X-ray images of the subject from different angles, wherein the set of markers are visible in the X-ray images;
reconstruct a 3D volume of the subject based on the plurality of 2D X-ray images; wherein at least a part of the set of markers is positioned outside volume covered by the reconstructed 3D volume of the subject;
identify at least the part of the set of markers in the plurality of 2D X-ray images based on image data of the plurality of 2D X-ray images outside the 3D volume and determine a spatial location of the set of markers in relation to the 3D volume of the subject;
register the reconstructed 3D volume of the subject to a current spatial position of the subject based on the current spatial location of the set of markers as detected by the marker detecting arrangement and the determined spatial location of the set of markers in relation to the 3D volume of the subject; and
provide the registered reconstructed 3D volume for navigation support.
