(Left) Reconstructed CT images as a function of Δθ. (a) Δθ = 1.0°; (b) Δθ = 3.0°; (c) Δθ = 6.0°; (d) Δθ = 12.0°; (e) Δθ = 24.0°; and (f) Δθ = 48.0°. The CT images were obtained from projections at the qy positions of 0.24 nm−1 in the in-plane profiles at qz = 0.80 nm−1. (Right) Recovered CT images using TV regularization for downsampling CT images: (g) Δθ = 3.0°; (h) Δθ = 6.0°; (i) Δθ = 12.0°; (j) Δθ = 24.0°; and (k) Δθ = 48.0°. |
