@craig Then there is also #TotalSegmentator: https://github.com/wasserth/TotalSegmentator

You can get it as a standalone command-line tool, a web application or as an extension to #3DSlicer.

Creates segmentations of 104 organs within a few minutes and also runs on CPU if necessary (lower resolution tho)

Totalsegementator - not only iis the tool open source but also available for 3Dslicer as an extension. Example segmentation of thorax on coarse setting (without GPU and an old Athlon CPU), takes < 5 min.
