From: Estimating view parameters from random projections for Tomography using spherical MDS
Illustration of Fourier slice theorem. The Figure illustrates the basics of Fourier slice theorem. The left figure shows the simulation of generating the projection from the view angle θ. The P θ denotes the projection from view angle θ. The right figure shows the Fourier transform of the image in the left. The green marked slice and the Fourier transform of P θ are equal according to the Fourier slice theorem.
