Thank you,
I tried that and I'm now getting pixel values that are more in line with what I had before. That said, values of contrast and MTF are still very different. Previously I would have gotten contrast values of ~1 and now they're ~4. And MTFs were on the order of 3.3 and now they're ~0.5.
The way that I report contrast is qc3.low_contrast_rois[4].contrast*100. (In the old code it was round(qc3.lc_rois[4].contrast * 100,3)). [it was stupid of me to pick [4] but let's ignore that) Did the ROI definitions (indexes) change at all? Did the calculation of contrast change? When I print out the ROI list they seem to come out in a different order in v2.3.2 compared to v2.2.7.
The MTF call I used before was qc3._mtf(50). Now I'm using qc3.mtf.relative_resolution(x=50). Is that the right way to call it? Not sure why the result should have changed so much.
Thanks in advance
