[Insight-users] Recommendation of algorithms for liver vessel extraction

[Xiaopeng Yang]

Dear ITK users,

I tried to apply region growing algorithm (connected threshold) to extract
portal vein, hepatic vein, and artery in liver from CT image. However, since
the intensity values of those three vessels are similar to each other, the
connected threshold algorithm cannot separately extract those three vessels,
furthermore, other organs are also extracted.

Does anyone of you have good ideas about this problem? Are there other
better segmentation algorithms to extract the three vessels separately?

Thank you for your help!

Best,
Xiaopeng
