Base class for forward projection, i.e. accumulation along x-ray lines.
ConstantProjectionStackSourceType::Pointer m_ConstantProjectionStackSource
Generate an n-dimensional image with constant pixel values.
Projection geometry for a source and a 2-D flat panel.
typename TOutputImage::RegionType OutputImageRegionType
Interpolates (linearly) in a 3D+t sequence of volumes to get a 3D volume.
ForwardProjectionFilterType::Pointer m_ForwardProjectionFilter
ConstantProjectionStackSourceType::OutputImageRegionType m_PasteRegion
Implements part of the 4D reconstruction by conjugate gradient.
