[Insight-users] ring artifacts in CT

[somi]

Hi,
I have some CT images which are severely degraded by ring artifacts during
acquisition .
The ring artifact looks something like :
http://www.upstate.edu/radiology/rsna/ct/images/artifact4.jpg (not my image)
, its more severe in my images.

Has anybody encountered similar artifacts ? Is there is any out of the box
way to remove them ?

Regards,
Somi
