"The Contrast to Noise Ratio was calculated from Formula 1 of Catphan Phantom’s low contrast module screen.

A 10 HU CT value difference in low contrast module, a 15mmφ rod ROIm, and an ROIb of identical size in the background area immediately inside this was set/configured."

or depending on how you're wording it the second sentence could be;

"We set/configured a 10 HU CT value difference in the low contrast module, a 15mmφ rod ROIm, and an ROIb of identical size in the background area immediately inside this."

So, The CT value difference of 10 HU was also 'set' in the low contrast module?

Is that how we interpret the the first part of the sentence? Or, should it be read

as 'for the CT value difference of 10 HU'?
