Hello All,

I am currently working on X-Ray CT images of soil within plastic columns (which have been spilt in half with mesh). See the attached image for an example. I am having problems removing the ring artefacts present within my images that will effect the analysis of pore spaces present within these soil columns. I have checked the archives of this mailing group and the plugins page for ImageJ and cannot find any evident solution to the ring artefact problem. I know that this is a common problem, so I hope that there is a solution out there someone which I have simply missed on my research.

Any help you can offer will be appreciated very much.

Thanks,
Sarah
