Purpose:Spectral computed tomography(CT) is known as a promising technique for obtaining enhancedimage with contrast agent.K-edge imaging is a useful method to distinguish different materials in spectralCT system.We focused on developing k-edge imaging for lower radiation exposure and shorter acquisitiontime by using sinogram interpolation.
