Vessel Segmentation in Slicer3
Project goal: Implementing a vessel/tube segmentation module in Slicer3
Kick-Off: 10/15/2008
Task 1: Module for Slicer3 based on old version
In Slicer2 exists a module called vtkExtractAirway. This module is based on a centerline approach documented in the following paper: "Aylward, S.: Initialization, Noise, Singularities, and Scale in Height Ridge Traversal for Tubular Object Centerline Extraction (available http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.18.8435)".
Since the algorithm is not fully implemented yet, the idea is to port the Slicer2 module to Slicer3 and finalize it to be used as a semi-interactive way to segment vessel or other tube shaped ROI.
The semi-interactive way should work like the following that a user clicks into a path of a ROI and then the algorithm computes all the connected tubes and highlights them.
Task 2: an interface to VMTK in Slicer3
VMTK is the Vascular Modeling Toolkit (http://vmtk.org) and offers interesting techniques for segmentation of vessels or tube-shapes.
It should be very interesting to offer such techniques in Slicer3. So the plan is to make a python scripted module that connects to VMTK pipes and provides even the possibility of user interaction.
