Detailed Description

template<class IntensityType = float>
class itk::ForwardProjectionWithAffineTransformDifferenceFilter< IntensityType >

Class to compute the difference between a reconstruction estimate and the target set of 2D projection images.

This class performs a forward projection of the input volume, calculates the difference between this projection and the corresponding slice of the input volume of 2D projection images and back-projects these differences into the output 3D volume. This process is repeated for each slice of the input volume of 2D projection images and the back-projected differences are summed.
