class tomocupy.rec_steps.GPURecSteps(args)

Bases: object

Class for a stepwise tomographic reconstruction on GPU with conveyor data processing by sinogram and projection chunks. Steps include 1) pre-processing the whole data volume by splitting into sinograms, 2) pre-processing the whole data volume by splitting into proejections, 3) reconstructing the whole volume by splitting into sinograms and projections The implemented reconstruction methods are 1) Fourier-based method with exponential functions for interpoaltion in the frequency domain (implemented with CUDA C), 2) Direct discretization of the pbackprojection intergral
