[Rtk-users] Question about RTK SART reconstruction

[Simon Rit]

Hi,
Thanks for your interest. Prefer the mailing list (cc) for your
questions. rtkSARTConeBeamReconstructionFilter
can use the GPU by setting GPU forward and backprojectors, simply set the
adequate projector. For example, check rtksart
<https://github.com/SimonRit/RTK/blob/master/applications/rtksart/rtksart.cxx>
the command line options
<https://github.com/SimonRit/RTK/blob/master/applications/rtkprojectors_section.ggo>
CudaRayCast, CudaVoxelBased are used to set GPU projectors. CudaVoxelBased
is the most efficient BP but CudaRayCast is matched to the corresponding BP.
Cheers,
Simon
