I would like to export results of TotalSegmentator into DICOM Segmentation format. I am using latest Slicer stable 5.2.1 on Mac. I loaded input CT series from DICOM Browser. I have QuantitativeReporting extension installed. However, segmentation results are not automatically placed properly in the …

Yes, it all works! Probably the reference volume was not set in the segmentation. I’ve tried to explain this in the message in the DICOM export dialog (see red text): [image] The solution is to specify segmentation geometry using the DICOM image as source: [image] I’ve now updated TotalSegmen…

[image] lassoan: We have implemented functions in Slicer for splitting/merging overlapping/non-overlapping segments that you might find useful for this. @lassoan can you help with pointers to those relevant functions in Slicer?

I started working on adding that functionality in Add support for saving segments in a single file by fedorov · Pull Request #464 · QIICR/dcmqi · GitHub
