Operating system: Windows 10
Slicer version: Slicer 4.11.20200930
I have a binary mask in a Nifti file and I want to convert it into a DicomRT structure. I have tried 3D Slicer to perform this conversion using Dicom export plugins. Also, I have found a package, RT-Utils, that deals with it. However, the resulted DicomRT structures of both tools are not exactly the same.
Can anyone give me some details about this exportation in 3D Slicer?
I think the problem may be due to the way of extracting/storing the contours (e.g., the interpolation method), which may be somewhat different for both tools, thus providing slightly different results.
Can anyone ensure me that the exportation in 3D Slicer is robust? Has it being tested with “round-trip” experiments from Nifti to DicomRT and back (from DicomRT to Nifti).
Thanks in advance.
