摘要

Image processing method is presented along with reference source code and sample outputs. This method processes 2 (or more) input images which were obtained at different photon energies (or differing in another parameter), and produces an output image that emphasizes the best characteristics of each of the input images, while suppressing the undesired characteristics of each input image. This is different from prior dual-energy CT methods which produce an intermediate compromise image, with an intermediate soft tissue contrast and intermediate artifact suppression, and also different from prior methods that sacrifice soft tissue contrast to maximize artifact reduction.
