Gammex Model 467 and HU linearity module ValueError

[James Han]

So I'm working on a custom phantom analysis.

I get the classic self.find_origin_slice() error "ValueError: No slices were found that resembled the HU linearity module"

Based on searching this forum, I should try placing my Gammex Phantom on a light density material to raise it away from the couch top?

Thanks in advanced!
