LightSpeed 4.X - Octane
Symptom
Soft ring artifact appears on all scans with no errors in the error log. See LD for details Soft ring artifact appears on all scans with no errors in the error log. The recon selected was BONEPLUS. Note that RINGFIX is not applied to bone or detail algorithms. This is the cause of why the soft tissue looks very noisy. This is normal for this recon as the window and level would generally be adjusted to view the bone - not the soft tissue.
