Detailed Description

template<class TInputImage, class TOutputImage = TInputImage, class TFFTPrecision = double>
class rtk::FDKConeBeamReconstructionFilter< TInputImage, TOutputImage, TFFTPrecision >

Implements Feldkamp, David and Kress cone-beam reconstruction.

FDKConeBeamReconstructionFilter is a mini-pipeline filter which combines the different steps of the FDK cone-beam reconstruction filter:

rtk::FDKWeightProjectionFilter for 2D weighting of the projections,
rtk::FFTRampImageFilter for ramp filtering,
rtk::FDKBackProjectionImageFilter for backprojection. 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.
