[Rtk-users] 回复：How to output the image after truncation correction and ramp filtering?

[Simon Rit]

Hi,
The FDK filter is a composite filter. The ramp filter, which does the
truncation correction, is one of the filters. You can simply do
feldkampCUDA->GetRampFilter()->GetOutput() to get this intermdiate result.
