The latter includes a first plurality () of first areas () with a first X-ray attenuation, and a second plurality () of second areas () with a second X-ray attenuation. The second X-ray attenuation is smaller than the first X-ray attenuation, and the first and second areas are arranged periodically in an alternating manner. A third plurality () of third areas () is provided with a third X-ray attenuation, which lies in a range from the second X-ray attenuation to the first X-ray attenuation, wherein every second of the first or second areas is replaced by one of the third areas.
