Image reconstruction methods

Image reconstruction methods#

Methods from httomolibgpu.recon.algorithm module are required to reconstruct the projection data, i.e., converting the set of sinograms into a reconstructed volume. The reconstruction methods can be divided into two groups: Direct analytical methods (Log-Polar 3D (ToMoBAR), FBP3D (ToMoBAR), FBP2D (ASTRA-Toolbox)) and Iterative methods (FISTA 3D (ToMoBAR), CGLS 3D (ToMoBAR), SIRT 3D (ToMoBAR)). The former are faster and suitable for the majority of well-sampled and well-exposed data, while the latter are more complex and slower methods suitable for erroneous, noisy or/and undersampled data.
