Detailed Description

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

Implements the Simultaneous Algebraic Reconstruction Technique [Andersen, 1984].

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

• ExtractFilterType to work on one projection at a time
• ForwardProjectionImageFilter,
• SubtractImageFilter,
• 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.

Two weighting steps must be applied when processing a given projection:

• each pixel of the forward projection must be divided by the total length of the intersection between the ray and the reconstructed volume. This weighting step is performed using the part of the pipeline that contains RayBoxIntersectionImageFilter
• each voxel of the back projection must be divided by the value it would take if a projection filled with ones was being reprojected. This weighting step is not performed when using a voxel-based back projection, as the weights are all equal to one in this case. When using a ray-based backprojector, typically Joseph,it must be performed. It is implemented in NormalizedJosephBackProjectionImageFilter, which is used in the SART pipeline.
