Implement Fourier-based direct reconstruction #27

Closed dkazanc closed 6 years ago

dkazanc commented 6 years ago

As an alternative to use ASTRA-toolbox to reconstruct data, implement Fourier direct reconstruction based on Fourier slice theorem for parallel beam geometry. It is suitable for well-sampled projection space.
