<div dir="ltr"><div><div><div>Hi RTK users/developers, <br><br></div>I've been using RTK for CBCT reconstructions and found it to be very useful, so thanks for all the work done on it!<br><br></div><div>As
for my question,when I use rtkadmmwavelets I get a ring artifact in the
center of the image. I'm using it for 4DCBCT reconstructions, so I'm not using the full number of projections and not sure if this is a contributing factor. From reading previous posts I know that the entire
object must be in the reconstruction, and so I have included both the
patient and couch in the reconstruction volume but still get the ring
artifact. Has anyone else encountered this? Any ideas/suggestions?<br></div><div><br></div><div>Cheers,<br></div>Joel<br><br></div>PS. When trying rtkadmmtotalvariation I don't encounter such issues.</div>
