CatPhan classifier was not able to identify the HU slice

Hi

I have problem trying to analyze Catphan images of a Philips Bigbore CTSim. I get this warning about HU slice identification and the program proceeds to use brute-force method. In some series it succeeded to find the slice but in other series it failed with this message: “No slices were found that resembled the HU linearity module”. I am quite sure all the image series are full images and well visualized on the CT and TPS monitor screens. Can someone help?

Hey,
I haven’t yet seen images from a philips bigbore, so there might be a bug holding up analysis. If you upload your images I’d be happy to look at them and see if I can fix the issue. You can upload them here. Thanks!
