Can I update the contours on a DICOM structure file?

Hi everyone, I am new to this software and I am wondering if I can achieve the following:

I’ve loaded a DICOM structure file (made in Python) with their respective CT images of a phantom into 3D slicer using SlicerRT extension. Some of the contours I made need adjusting and I’m wondering if 3D slicer can overwrite the new segmentations over the old triplet coordinates in the DICOM RT structure file?

Thank you in advance.

Yes, sure this should be no problem at all. This is why DICOM RTSTRUCT import/export features in SlicerRT extension and the Segment Editor module were developed for.

Thanks for your reply. That’s brilliant. I right clicked “Export to DICOM” in the study module, clicked RT as type and exported. It did the trick :slight_smile:
