Radial-acquisition imaging is recently gaining more popularity. For RA image reconstruction, both fast Fourier transform via gridding and filtered back-projection are available. Because of the processing time, FFT is dominantly used. If the processing-time issue is resolved, 3D FBP can be promising in the case of FID sampling or echo sampling with mis-centering of k-space. In this study, we propose a strategy that can significantly reduce the reconstruction time of 3D FBP in combination with a new RA scheme. Performance of the proposed method was demonstrated in phantom and human brain imaging at 3T.
