| abstract | More accurate beam hardening correction is performed with a low computational load on objects having a wider range of elements with effective atomic number Z eff , which contributes to the presentation of more quantitative X-ray images. The X-ray attenuation amount μt of the two X-ray energy BINs selected from the two or more X-ray energy BINs is standardized, and at least one standardized X-ray attenuation amount is obtained for each pixel region, and the standardized X-rays are obtained. At least one effective atomic number is estimated for each pixel region from the reference information showing the theoretical correspondence between the attenuation amount and the effective atomic number of the element, and the estimated at least one effective atomic number (Z High , Z). It is determined that at least two atomic numbers of the low ) and the effective atomic number (Zm) specified in advance when performing beam hardening correction are matched. |
