I loaded DICOM-RT using DICOM module. When I turned to Data Module, the RT structure was shown as a segment. Can this segment used as input region in radiomics calculation? I am a little confused about that. RT-Struct are planar contour, it is not a volume. But when I use it to do the radiomics calculation, I get the same answer as I use the labelmap (I use the segmentation module to export the labelmap from segment) as input region. Many thanks.
