<p>An X-ray CT image processor which performs beam hardening correction of bones at high speeds and easily based upon the reconstructed image data only. Bone region in the reconstructed image is determined based upon the reconstructed image data, and a two-dimensional weight function is subjected to the mask addition or to the convolution with the thus determined bone region as a mask, in order to find image data for correction. The image data for correction are then added to the reconstructed image data.</p> |
