ρ) is the slice view of F(u, v) (the 2D Fourier transform of f(x, y)) passing through the origin and along θ₀ + π/2. Each column in Figure 4 generates a 1D spectrum that gets pasted in a 2D spectrum F(u, v). Having a large number of projections, we can build a “radially dense” 2D spectrum (Cf. Fig.
