Hi Slicer Developers
I was able to extract the sections of rods installed in a phantom in MRI images using “Segment Editor” module and “Thresholds” effect.
Its output can be of type “Model”. At now, I want to extract centerlines of these rods using “ Centerline Computation” module. It seems for using this module, I MUST define fiducials as the origins of these centerlines in this module.
The number of these rods is high and doing it depends on the person (subject dependent) and time-consuming. I want to do it without choosing start points as origins. How can I do it?
Please guide me.
VMTK extension’s centerline computation module requires only one root point as input and it returns all centerline endpoints as output.
There is also a fully automatic MRI phantom registration method (that computes position and orientation of a phantom consisting of sticks fiducials) available in ProstateTracker extension - https://github.com/SlicerProstate/SliceTracker/blob/master/README.md
