The 3D seeding procedure. A The gold markers are inferred as the main convergence nodes of back-projected rays arising from the detected projection peaks. B In practice, a cluster analysis is performed on the mid-points of the shortest segment joining selected pair of back-projected rays. Note that the two paths \(\omega _1\) and \(\omega _2\) do not necessarily cross in 3D
