[Rtk-users] Helical scan

[Simon Rit]

Hi,
The RTK geometry does support the description of any scan. You can just
provide the 3D coordinates of each source and detector positions with the
method AddProjection
<https://www.openrtk.org/Doxygen/classrtk_1_1ThreeDCircularProjectionGeometry.html#a0fb1475ed76a28cde24fac85eae18e1e>
.
All iterative reconstruction algorithms will be to use any geometry.
However, there is no filtered backprojection algorithm for helical CT
reconstruction. The work had been started but has been stalled for a few
years now, see
