[ITK] Convert stl to DICOM

Tue Mar 14 04:56:04 EDT 2017

Hi Andras,

I am working on a visualization software that due to the infrastructural constraints can only take DICOM images as input. As a result I am looking for ways to convert the mesh output of some of our algorithms to DICOM. So to answer your question: No I am currently not aware of any other software that can do that and I am still in the planning phase. I could imagine, however, that with virtual reality, surface representation will become more important in the future.

Thank you for your help,

Markus

Hi Markus,

What do you plan to do with the surface exported to DICOM?

RT structure sets are widely supported, but segmentation objects are relatively new. Do you know about any software that can read or write DICOM Surface Segmentation IOD?

Hi Dženan and Andras,

Thanks for your replies, I am looking for a way to save a polygonal surface. I am not sure yet if a conversion to an RTSTRUCT or even a binary image would suffice, it would not ideal though.

Best,

Markus

Currently Slicer supports these IODs for saving segmentations (both labelmap-based):
http://dicom.nema.org/medical/dicom/current/output/chtml/part03/sect_A.51.html
http://dicom.nema.org/dicom/2013/output/chtml/part03/sect_A.19.html

If there is a need, we can add Surface Segmentation IOD, too.

Hi Markus,

did you refer to DICOM polygonal surface<http://dicom.nema.org/dicom/2013/output/chtml/part03/sect_A.57.html> format? Or just binary DICOM image?

Andras, can slicer write this<http://dicom.nema.org/dicom/2013/output/chtml/part03/sect_A.57.html>?

Regards,
Dženan

3D Slicer (www.slicer.org<http://www.slicer.org>) should be able to do this conversion: it can import STL files that you can either convert to segmentations or fake images and then export to DICOM. Write to the slicer-users mailing list if you get stuck at any point.
