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.
