1. A method for displacement tracking during positioning and fixing of an implant in a bone, in particular in a hip bone, the method comprising:
superimposing an image of the bone with at least one reference image, wherein the image of the bone is taken from a first angle and the at least one reference image is taken from a second angle, wherein the difference between the first angle and the second angle is no more than 5°;
visualizing a relationship between the image of the bone and the at least one reference image for tracking a displacement of the bone relative to an implant;
distinguishing between primary structures and non-primary structures in the image of the bone and in the at least one reference image; and
removing the non-primary structures and depicting only the primary structures in the image of the bone and in the at least one reference image;
wherein each of the primary structures is at least one of a bone, a bone shape, a bone fragment, an implant, a reference body and/or an additional reference object.
