Somatom Volume Zoom Ring atifact

August 09, 2019 10:02

Hello
The images show ring artifact, I already did air calibration and the problem persists. I tried to make channel correction, but it shows the following message:
... calculating channel correction values failed, possibly caused by a defective channel...
What are the steps in the software to find and disable the defective channel?
Software version: Somaris/5 VA47C
I appreciate the help you can give me.

I believe he already made that conclusion Eric . I think hes not sure how to troubleshoot the specific detector board. Do you have any tips? I'm no Siemens expert.
