Hello, I was using 4.10.2 to convert stl to DICOM. However, after update to 4.11.2 I could not fund functionality. Can anyone help me with this? Thank you, Amy

See step-by-step instructions for DICOM export here https://slicer.readthedocs.io/en/latest/user_guide/modules/dicom.html#export-data-from-the-scene-to-dicom-database If you have any specific questions then let us know.

Can you please share the tip? Thank you!

Thank you for sharing. The file I need to convert is a stl file and when I follow the instruction (right-click to “Export to DICOM”) there is no option to select the export type in the bottom left of the export dialog. I need to convert the stl file to an RT structure set. Do you mind giving me more…

You need to convert it to segmentation first. You also need the associated CT image - RT structure sets cannot be generated and interpreted without a referenced CT.

How do I create an associated CT image? Do I import one to the software? How do I make them associated? in 4.10.2, I only need to do “Mesh to Lable Map” and then I can export it as a DICOM file. Thank you again for your help!

I assumed you already have a CT image that the STL model was derived from. You can of course create a fake CT for it, but to tell if it is the right answer, we would need to know what you would like to achieve at the end. What is the overall goal of your project? Why do you need to convert STL file…

I use a 3D camera to capture the patient’s body contour which was truncated by CT (limited CT FOV). With the 3D captured body contour we can make up for the missing information. I want to import the 3D scan as an RT-struture to the TPS and fill up the missing tissue with the water. Thank you!

or… can it be converted to a “CT scan”? I think it was working in that way in the old version? Or… is there any chance I can download the 4.10.2?

You can load the CT, expand it using Crop volume module and a ROI, register it to the surface scan, and use Mask volume effect (provided by SegmentEditorExtraEffects extension) to fill the region inside the surface scan with 0 HU. You can then export this modified CT to DICOM and use it in your trea…

Do I have to load the CT? Can I just convert the stl to DICOM? I can register them in the TPS. Thank you!
