Alternative reconstruction algorithm for NMR imaging
- 35 Downloads
A new algorithm for image reconstruction is proposed. Because a varying sampling increment is introduced, the interpolation during reconstruction is eliminated and the Fourier transform from modified polar to Cartesian sample grid is applied. The comparison of the back-projection of filtered projections method with the proposed PCFT algorithm is performed on computer-simulated data. Good resolution of the reconstructed images and a relatively short reconstruction time are the merits of the newly developed technique NMR imaging is cited as a possible field of application of the algorithm.
