[Rtk-users] rebinning

[Cyril Mory]

Hi Niloufar,

There is no such program in RTK, and you won't find it anywhere else. 
What you are asking for is impossible.
In 2D fan-beam, rays can be sorted into groups of parallel rays, because 
they are indeed parallel to each other.
In 3D cone beam along a circular trajectory, the rays outside the 
central slice cannot be sorted into groups of parallel rays : they just 
aren't parallel.

Hope that helps.

PS : The more I think about it, the more I think there must be some 
connection between the possibility of re-binning to parallel projections 
and Tuy's data sufficiency condition. If someone has a clear 
understanding of this area, I'm curious about it.
