It solves the problems, such as: being rebuild to reduce pseudomorphism in computed tomography image.SOLUTION: this method comprises: obtaining original reconstructed image and original acoustic wave figure and determining the reconstruction image of the metal pixel original text of ratio If the ratio of metal pixel is greater than first threshold, then generate the original reconstruction image of template of expansion, it generates without metal, metal artifacts and reduces (MAR) based on expanded metal template and initial sinusoids figure, final image is generated, the image reduced based on the expanded metal template with without metal, metal artifacts But, if the ratio of metal pixel is less than second threshold, then generate the original reconstruction image of template of expansion, it generates without metal, metal artifacts reduced image and is based on treatment, including weighting metal lath template and initial sinusoids figure, final image is generated, based on the expanded metal template and without metal, metal artifacts downscaled images.COPYRIGHT:(C) 2015, JPO& INPIT
