Claim 14:
15. A method of generating a tomography image, the method comprising:
acquiring N pieces of projection data respectively corresponding to N views included in a first angular range;
generating a first image by back-projecting N edge images respectively representing edge information in the N pieces of projection data;
generating a first corrected image by correcting a pixel value of a region corresponding to a material having a high X-ray attenuation rate compared to its surrounding region included in the first image for the first angular range;
generating a frequency modulation-transformed first corrected image by performing frequency modulation transformation on the first corrected image for the first angular range;
generating a filtered back-projection image by performing filtered back-projection on the N pieces of projection data for the first angular range; and
generating a final tomography image for the first angular range by blending the frequency modulation-transformed first corrected image with the filtered back-projection image for the first angular range.
