Detailed Description

template<class TInputImage, class TOutputImage, class TDeformation>
class rtk::FDKWarpBackProjectionImageFilter< TInputImage, TOutputImage, TDeformation >

CPU version of the warp backprojection of motion-compensated FDK.

The deformation is described by the TDeformation template parameter. This type must implement the function SetFrame and returns a 3D deformation vector field. FDKWarpBackProjectionImageFilter loops over the projections, sets the frame number, updates the deformation and compose the resulting deformation with the projection matrix. One thus obtain a warped backprojection that is used in motion-compensated cone-beam CT reconstruction. This has been described in [Rit et al, TMI, 2009] and [Rit et al, Med Phys, 2009].
