Detailed Description

template<class TInputImage, class TOutputImage>
class rtk::FDKBackProjectionImageFilter< TInputImage, TOutputImage >

CPU version of the backprojection of the FDK algorithm.

CPU implementation of the backprojection step of the [Feldkamp, Davis, Kress, 1984] algorithm for filtered backprojection reconstruction of cone-beam CT images with a circular source trajectory.
