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.
The former are faster and suitable for the majority of well-sampled and well-exposed data.
The latter are more complex and slower methods suitable for erroneous or/and undersampled data.
