ABSTRACT:
An X-ray marker includes a shaping material formed with a base having a substantially constant thickness and pattern formed in the base having a thickness different than the base. An X-ray attenuator is suspended in the shaping material creating a composite material having a substantially uniform density. The X-ray absorption of the base varies in proportion with the base thickness. Therefore, the different thicknesses of the base forms an image corresponding to the pattern when the marker is disposed over an X-ray sensitive image receptor and exposed to X-rays.
