Classification: CPC G  A | IPC G

Claim 11:
12. The method of claim 1, further comprising:
generating a first image by correcting, based on the final weight map, N edge images generated by respectively performing edge enhancement for edge information in the N pieces of projection data and then back-projecting the corrected N edge images;
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;
generating a frequency modulation-transformed first corrected image by performing frequency modulation transformation on the first corrected image; and
generating a filtered back-projection image by performing filtered back-projection on the N pieces of projection data,
wherein the generating of the final tomography image comprises
generating the final tomography image by blending the frequency modulation-transformed first corrected image with the filtered back-projection image.
