Objective
To create a Slicer-based platform for segmentation of vascular segments from angiographic images (CTA, MRA, ...), analysis of vascular geometry, mesh generation, computational hemodynamics (CFD) and visualization.
Approach, Plan
To integrate vmtk scripts within Slicer as command-line modules for the non-interactive tasks, and to create ad-hoc GUI modules for the more interactive tasks (i.e. segmentation).
The plan for the project week is to finalize the implementation of an interactive LevelSetSegment module that replicates (and improves) the interactive segmentation tool currently in vmtk. Tentatively, LevelSetSegment will be a Python Scripted Module.
Progress
During project weeks last year (see 2007 Project Week at MIT), automated conversion of vmtk script pipes to Slicer command-line modules has been implemented.
During June 2008 project week, the architecture of the new LevelSetSegment module has been finalized. A new vtkMRMLLevelSetNode, subclass of vtkMRMLScalarVolumeNode, has been introduced. The corresponding display node directly displays the poly data corresponding to the level set surface. The final implementation of the module (except the new MRML nodes) will be converted to a Python scripted module.
