Objective

The Vascular Modeling Toolkit (VMTK) is a collection of libraries and tools for 3D reconstruction, geometric analysis, mesh generation and surface data analysis for image-based modeling of blood vessels.

Main goal of the incorporation effort for the upcoming 3D Slicer version 4 is the enhancement of the modules' usability and in particular the focus on reducing the required user-interaction.

Approach, Plan

One single extension bundle called SlicerVmtk4 will provide a package of all VMTK libraries and modules. We want to use the 3D Slicer4 extension infrastructure for distribution and will try to achieve this during the project week.

In terms of usability each module now has a preview mode which displays results in less than 10 seconds. Also, beside seed points, only max. one parameter is required. If desired, more parameters are available in an advanced mode.

Progress

The SlicerVmtk4 extension uses the Superbuild mechanism to download the VMTK libraries. This was not supported by the extension infrastructure yet so we worked on that during the project week with Slicer4 Core Developers. We are very close to finish it and then this extension will be included in the Slicer4 Nightly builds.
