We investigated an image reconstruction algorithm to reduce cone-beam artifacts in cone-beam CT. Our new algorithm to reduce such artifacts features: (1) a change in weighting with respect to projection data obtained at different projection angles; (2) distribution of correction coefficients so that they are larger near the center of the detector, while taking individual channel data for the detector into account, and smaller near the edges; (3) three-dimensional back-projection of corrected projection data. These findings confirmed that this algorithm reduces cone-beam artifacts and generates high-quality reconstruction images. |
