Find needle tip position automatically by segmentation during needle insertion

s12359e · February 21, 2019, 7:03am

Operating system: Win10
Slicer version:4.10.0
Expected behavior:

I make the needle insertion to the phantom as the picture shown.

.
I wanna find the needle tip location automatically by segmentation or sort of that.
I try “needle finder” this extensions but I hit “start Giving control point” it didn’t work.
Now i just manually put the fiducial point on the slicer and find the tip position.

Does anyone know how can I figure it out by another methods?

Thanks a lot!

Hello, may I know how to configure the needle finder file in my computer? Thanks!

NeedleFinder project repositories are available here:

A simple fully-automatic needle detection algorithm is also discussed here:

If you need to find contrast-filled markers (not needle voids) then you may find the robust tubular marker detection algorithm in ProstateNav useful:
