Abstract :
Three O(N3 log N) types of 3-D reconstruction methods from Radon data are presented. All of these employ the direct Fourier methods with linogram sampling. The Grangeat two-stage method is for the foundation of the first and second methods, while the third type is more truly a 3-D direct Fourier method
