[Rtk-users] helical cone-beam CT reconstruction

[Simon Rit]

Hi Dennis,
You can do a helical trajectory and I have used our iterative
reconstruction tools in this work
<http://www.creatis.insa-lyon.fr/~srit/biblio/clackdoyle2017.pdf> to do
helical reconstructions. It works. However, RTK does not have any filtered
backprojection reconstruction for helical CT.
You can check FreeCT <http://dx.doi.org/10.1118/1.4941953>, I think that
what it does.
