CATphan with CT

[Stephen Amadon]

I'm using the CATphan on the CT and some months it "sees" the couch and other months it does not.  Is there a remove couch option?

I included some screen shots from the report.  you can see the couch included and hot it affects the uniformity graph.

Thanks,

Steve

I've played around and changed my FOV of the scan and it adjusted the results to remove the couch.  Interstling, the MTF for line pairs increases from .25 to .35.  This difference is what made us look into why the results looked differently.

Attached are the 2 different reports to show the difference.

Thanks,

Steve
