[Rtk-users] Forward and Back projections in 3D parallel geometry

[Yannick BOURSIER]

Hi all, 

In an old archive (March 2013), it was announced that only rtkfdk was working correctly with a parallel beam geometry (defined by artificially setting the SourceToDetectorDistance to 0.).

It seems that it is still not possible to execute forward and backward projections with such a geometry, is it true, or did I miss something ? I've just checked all the archives without finding any clue about that problem.
Could you help me please ?

Thanks in advance, 
Best
