I want to create lumen and plaque inside an arterial wall(similar to the structure in attached file).So it will be a hollow wall and lumen inside it(fixed,no spaces between them).How can i do it in slicer?
To create vessel wall, use “Hollow” effect in recent nightly version of Segment editor. If you import model or labelmap from other software then you need to import it into a Segmentation node. Let us know if you stuck at any point or you don’t get good enough quality segmentation.
Uninstall previous Slicer if found then remove Slicer configuration folder manually. Install Slicer. It should works.
To get the best result, resample your volume (using “Resample Scala Volume” module)to iso then resample to a higher resolution e.g. 0.06,0.06,0.06. Then use Hollow with the minimum shell thinness.
P.S:
- It is also useful if you provide more details e.g. your operating system and the error message.
- Edit your post and reply to look more nice. If you don’t put effort to write your question, probably no one will put effort to write an answer.
Hi, I’m looking to make similar segmentations. What procedures and tools did you use? Thanks!
You may use many modules like in this video.
The arterial wall is not a CT structure, it’s too thin, even diseased ones. You can however estimate the wall’s location, based on contrast, lesions and known anatomical shape of an artery. It’s an estimation. If you need 100% accuracy, you’re out of luck, even opening the patient won’t help you, alive or dead.
The Shape module of the ExtraMarkups extensions allows you to draw a Tube of varying radius, with which you can draw the wall at best estimate. Then you can do many things.
Admittedly, I do that fast for reasons. If you want to go that way seriously, make a few months allowance to learn all these tools. The benefit is lasting.
If you look towards AI, my bet is that’s it’s not ready yet for this kind of processing, maybe in 25 years, it will certainly mature; this does not mean it will be a sort of a new deity!
