Figure 15
(a) With a parallel beam, the one-dimensional Fourier transform of a one-dimensional radiograph of a two-dimensional object at angle [theta]

is equal to the one-dimensional slice at angle [theta]

in the two-dimensional Fourier domain of the two-dimensional object. (b) Sampling in the Fourier domain; the blue and red lines shown on the figure are the angular and radial sampling steps.
