摘要：
A user is visually assisted when fixing an implant with a locking element in, or on, a bone. The location of a guide instrument for guiding the locking element relative to the implant is set by a target apparatus. The implant can be rotated and/or positioned by moving the target apparatus. The guide instrument carries at least one x-ray marker. An x-ray device records an x-ray image of the target region of the locking element and the x-ray marker. The orientation and position of a projected straight line, which forms a projection of a longitudinal axis of the guide instrument in the image plane, is determined from the position and/or form of the image of the x-ray marker. A superposed illustration is calculated of the x-ray image with a graphical element indicating the orientation and position of the projected straight line and the superposed illustration is output on a display.
