Hi

I am looking for a ready-to-download surface model of liver vasculature. Only the arteries (PHA, RHA, LHA and their child segments) are required for radioembolization simulation. Is there a sample to download?

Hello @orxshi

we are working in a Slicer extension that can be used to generate this data ([Slicer-Liver](https://github.com/ALive-research/Slicer-Liver)). This week we will be available in [Project Week 37](https://projectweek.na-mic.org/PW37_2022_Virtual/) if you would like to have a chat on it. There is also a nice project ([RVesselXLiverSegmentation](https://github.com/R-Vessel-X/SlicerRVXLiverSegmentation)) which is somehow complementary to our work.

When it comes to data. We have models based on veins, not arteries. The segmens can be computed with the Slicer-Liver extension that we will try to release during this week in the extension manager.

Rafael

I have tried to use RVesselXLiverSegmentation but extracting arteries and veins is beyond my anatomy knowledge. Until I get together with my doctor friend I need a ready-made model of arteries/veins. However, at this stage I am also OK with any branched tubular geometry resembling arteries or veins.

Can Slicer-Liver extract veins from CT scans without user intervention?

I see. Do you only need a single model? Slicer-liver comes with a testing dataset of 1 liver with segmented portal/hepatic veins. 3D reconstruction of that is automatic in 3D Slicer and with Slicer-Liver you could use the segments extraction to manually extract the segments. Segments extraction is not very tedious and hopefully will be ready during this week.
