Detailed Description

template<class TVolumeImage, class TProjectionImage = TVolumeImage>
class rtk::OSEMConeBeamReconstructionFilter< TVolumeImage, TProjectionImage >

Implements the Ordered-Subset Expectation-Maximization algorithm.

OSEMConeBeamReconstructionFilter is a composite filter which combines the different steps of the OSEM cone-beam reconstruction, mainly:

ExtractFilterType to create the subsets.
ForwardProjectionImageFilter,
DivideImageFilter,
BackProjectionImageFilter. The input stack of projections is processed piece by piece (the size is controlled with ProjectionSubsetSize) via the use of itk::ExtractImageFilter to extract sub-stacks.

One weighting steps must be applied when processing a given subset:

each voxel of the back projection must be divided by the value it would take if a projection filled with ones was being reprojected.

By default the quadratic penalization described in [De Pierro, IEEE TMI, 1995] is applied during the iterative process. The hyperparameter for the regularization can be changed using the SetBetaRegularization method. If the hyperparameter is set to 0 the filter behaves like the classic MLEM/OSEM algorithm.
