Hello, how can I convert RTStruct to DICOM Seg? I’m having some difficulties…
You can load the RTStruct in Slicer if you have the SlicerRT extension installed. Then as far as I know you can export it to DICOM SEG if the QuantitativeReporting extension is installed, but I have never done this myself. See detailed information on DICOM exporting here: DICOM — 3D Slicer documentation
