2011 Winter Project Week:MIDAS for data hosting

• 

  Projects List

Key Investigators

• Kitware: Zach Mullen
• UIowa: Hans Johnson

Objective

Make use of the MIDAS data archiving system to host data related to tests such as baseline and comparison images. TubeTK is a new open-source toolkit that hosts algorithms for applications involving images of tubes.

Two driving applications:

• Surgical guidance: registering pre-operative vascular models with intra-operative images (e.g., ultrasound)
• Characterizing vascular patters: using graph theory to distinguish clinical populations based on vascular patterns (e.g., benign -vs- malignant tumors via tortuosity)

History

• June 2001, UNC released the patent on vessel extraction method from [Aylward, Bullitt 1996...]
• TubeTK released under Apache 2.0 license: includes rights to patents

Approach, Plan

• Python module in Slicer 4 for centerline and radius estimation of vasculature in brain MRA
  • Workflow: brain envelop segmentation, seeding, extraction
• Integration with VMTK

Progress

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as follows:

• All software written during the project week will be contributed to TubeTK, and algorithms will be incorporated into 3D Slicer as CLI applications.
