Abstract
A computer-implemented method of determining a rotational position of an object in a coordinate system of an x-ray imaging device is provided. An x-ray image is generated of an object to which a Moiré marker for x-ray imaging is attached. The Moiré pattern generated by the Moiré marker is analysed and the rotational position of the marker and hence of the object is determined in a calculative manner. The Moiré marker for x-ray imaging includes a pattern which results in a significantly different appearance when being observed from slightly different perspectives. The Moiré marker for x-ray imaging can include two layers with patterns produced by a material that shields x-ray as good as possible, surrounded and spaced apart by material that is highly transparent in x-ray.
