Meaning of values in pancs_4dct_phase6.npz

[lucasdevries]

Hi,

Thanks a lot for your exciting work. I was wondering what the values of the arrays in ancs_4dct_phase6.npz mean. The range is [0, 0.05]. It does not correspond to Hounsfield Units. How were the HU values (the intensities) converted to this range?

Thanks a lot!

The CT image is processed by converting the HU values to the linear attenuation coefficient according to the definition and parameters provided in the dicom scan.
