NA-MIC VMTK Collaboration

Collaboration with Luca Antiga of the Mario Negri Institute.

Key Personnel

• Luca Antiga
• NA-MIC: Ron Kikinis, Steve Pieper

Goals of the Project

To create a Slicer-based platform for segmentation of vascular segments from angiographic images (CTA, MRA, ...), analysis of vascular geometry, mesh generation and hemodynamic simulation (CFD) and visualization.

Since many of these functionalities are already provided by the Vascular Modeling Toolkit (www.vmtk.org) as command-line tools, the plan is 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).

Current progress

• vmtk script for automated conversion of vmtk command line pipes to Slicer command-line modules (DONE)
• Implementation of vmtk-based interactive modules, available at the VMTK in 3D Slicer project page. Documentation is available at the Slicer wiki here.
