Title:
Image processing equipment, radiation tomography equipment and programs
Document Type and Number:
Japanese Patent JP6293713
Kind Code:
B2
Abstract:
To reduce variability in a result of correction by beam-hardening correction in a radiation tomographic image: There is provided an image processing apparatus comprising: a first-index obtaining component configured to obtain, for each individual subregion in a beam-hardening correction-processed image representing a body region including a bone part and a soft part, a first index indicating how much beam hardening due to the bone part affects the subregion based on pixel values at a plurality of positions surrounding the subregion and a distance from the subregion; a determining component configured to determine an amount of correction on a pixel value for the subregion using the first index for the subregion; and a pixel-value correcting component configured to correct the pixel value of the subregion according to the amount of correction on the subregion.
