FAST RECONSTRUCTION ALGORITHM FOR CONE-BEAM CT |
摘要 |
A fast reconstruction algorithm for cone-beam computed tomography is presented. The algorithm is of the filtered backprojection type and uses nonuniform fast Fourier transforms to switch between functions defined and uniformly sampled on the detector plane and the Fourier transforms of these functions, sampled on a polar grid in the associated Fourier plane. |
