Oggetto: Ring Artifacts correction

 

Dear Rtk users and developers,

I have a set of projections that suffer both from truncation and ring
artifacts.
While for the first issue I’ve been fiddling with the --pad option to a
satisfying result, I’m unsure what would be the best way to deal with the
ring artifacts in RTK.
I’ll attach a screenshot of the sinogram showing evident strikes and an
animated gif with the resulting reconstruction highlighting the concentric
rings.

Thanks in advance for your help and input!

Gabriele Belotti
