Objective

We are developing a stenosis detector based on VMTK in Slicer 4. The goal is to be able to visualize stenosis after a vessel segmentation using a wizard-based interface.




Approach, Plan

Our approach for developing the stenosis detector is: first vessel enhancement, level-set segmentation, network extraction and then quantification and visualization of stenosis.

The tool will be evaluated on datasets.

Progress

A prototyp of the graphical user interface has been designed and implemented.

Project Week Update: The week was very productive. We got a lot of feedback from the Kitware guys. Specially on the wizard interface which is based on the CTK library. We also had to clarify an issue concerning the area of the wizard content and the way the different wizard steps interact with each other and with the logic.
