3-D Reconstruction

In order to obtain a 3D reconstruction, equally sloped tomography (EST) was utilized. The reconstructions required diffraction patterns at angles corresponding to a pseudo-polar grid. From the Fourier slice theorem, these reconstructions correspond to 2D projections which are converted to Fourier slices in the pseudo-polar grid. Then, by applying the inverse pseudo-polar fast Fourier transform (PPFFT) a 3D reconstruction is obtained [5][6]. Four images were taken at 0, 10, 20, and 30 degrees. The final result can be seen in figure 10. This was done as more of an attempt at 3D reconstruction, which was accomplished though the final product is not conclusive enough to determine what the subject was.
