Hello everyone,
I am Dr.RUPEN RAJVIR , BHMS, currently in the process of learning OAR (Organs at Risk) contouring using 3D Slicer.
My present work is purely for training and research purposes (non-clinical), and in the future, I plan to develop an outsourcing support service for OAR contouring using 3D Slicer.
I would be very grateful for your technical guidance on the following points:
Recommended modules or extensions for automatic or semi-automatic OAR segmentation (e.g., Lung, Heart, Liver, Spinal Cord, etc.).
Correct workflow for RTSTRUCT DICOM export — especially for ensuring geometry matches, metadata fields, and compatibility with TPS (like Monaco or RayStation).
Any best practices for structure naming, DICOM metadata, or data integrity when exporting for radiotherapy planning.
If there are any tutorials, example cases, or workflow videos you could recommend, that would be very helpful.
Thank you for developing and maintaining such a powerful platform for medical image processing!
With regards,
Dr. [RUPEN RAJVIR]
