This link provides everything required for my initial development. I now want to test my own CT data. But I am not sure how to do this model inference in Slicer. My data is in DICOM format.
Probably the easiest for testing would be to load the dicom data in slicer and export it in whatever format the python code requires (probably nii or similar) and then run the code outside of slicer and load the results back for visualization. You may need to work with the authors of that model to learn how to run it. From a quick look that code looks good, but it was set up for the publication but not as a ready to use tool without more work.
