| 主权项 | 1. An evaluation aid adapted to be used for taking a digital X-ray image thereof, wherein evaluation is carried out through the digital X-ray image, the evaluation aid comprising: a plate-like body being formed by laminating plates having different planar sizes together, the plate-like body including a plurality of regions having different X-ray absorption ratios, the different X-ray absorption ratios being obtained by at least different thickness of the plurality of regions due to differences of the number of the plates contained therein; and block-like bodies provided on the plate-like body so as to correspond to the plurality of regions, respectively, each block-like body including a plurality of subregions having different X-ray absorption ratios. | ||
