Abstract:
1. A method of generating a reconstructed 2D image of a 3D scan volume f(x,y,z) of an object, for an orientation (θ, φ, φ) of the 3D scan volume f(x,y,z), the method comprising: a. generating 3D scan data representative of the 3D scan volume f(x,y,z) of said object; b. computing a 3D Fourier transform F(u,v,w) of the 3D scan volume f(x,y,z), wherein u,v, and w are variables in a three-dimensional frequency domain; c. sampling a surface S(θ, φ, φ, u′, v′) within said 3D Fourier transform F(u,v,w), at angles (θ, φ, φ) corresponding to said orientation of said 3D scan volume; and d. computing the 2D inverse Fourier transform F
