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.

Parts of VMTK exist as 3D Slicer extensions and f.e. can be combined to a pipeline for centerline extraction of vascular trees. This pipeline consisting of Vessel Enhancement filtering, level set segmentation and the actual centerline extraction was tested on different cases.

Approach, Plan

The plan for the project week is to create a new VMTK based module for network extraction of vascular trees. Network extraction is comparable to vessel centerlines with a little bit less accuracy but faster. The algorithm works on a triangulated surface of segmented vessels and would fit in the pipeline of existing VMTK modules.

Progress

The following VMTK in 3D Slicer extensions already exist:

• VmtkSlicerModule prerequisite install for all VMTK plug-ins
• VMTKCenterlines providing centerline computation of surface models
• VMTKEasyLevelSetSegmentation providing level-set segmentation of vessels, aneurysms and tubular structures using an easy interface
• VMTKVesselEnhancement providing vessel enhancement filters to highlight vascular or tubular structures
