Detailed Description

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

Implements the ramp image filter of the filtered backprojection algorithm.

The filter code is based on FFTProjectionsConvolutionImageFilter by Gaetan Lehmann (see http://hdl.handle.net/10380/3154)
