摘要:
Disclosed are a multi-energy x-ray system, an image processing apparatus for discriminating a multi-energy x-ray material, and an image processing method for material discrimination of a multi-energy x-ray system. The image processing apparatus for discriminating a multi-energy x-ray material according to one aspect of the present invention comprises: a table for recording attenuation information and multi-energy x-ray spectrum information which correspond to one or more materials an initial image estimating portion for estimating an initial image of each of the materials with respect to a projection image of each of the energy bands generated when a multi-energy x-ray spectrum passes through a detecting target formed with one or more materials and an image update portion for updating the initial image as the material discrimination image using the estimated initial image and the spectrum information recorded in the table and the attenuation information recorded in the table.
