Good afternoon!  
I’d like to inquire about how to import segmented structures from 3D Slicer into Monaco (in DICOM) and ensure they are displayed as contours (Structures). I am unsure whether Monaco supports working with segmentations created in third-party software.

Could you please provide guidance on this matter?

Thank you in advance!
