Project Description
Objective
- Develop a Slicer module that automatically segments the left atrial wall from a given LGE-MRI image.
Approach, Plan
- Involves Bayesian formulation with Markov random field prior within a nested-layer 3D mesh which leads to surface-net problem [Veni et al, IPMI 2013].
- Solved by using VCEnet strategy and graph-cuts [Wu and Chen, 2002].
- Uses training strategy in order to generate model shapes as well as to compute costs at each mesh point.
Progress
- The module now provides the ability to the user to select the approximate center of the left atrium and the model is aligned with that point.
- The VCEnet technique produces better results than the Vnet technique that was used in previous versions of the module.
- Module is now available in the Slicer. It could be downloaded from: https://github.com/carma-center/carma_slicer_extension/
- The online documentation on its usage is available at: https://www.slicer.org/slicerWiki/index.php/Documentation/Nightly/Modules/AutomatedLASegmentation
- Model data could be downloaded from: http://slicer.kitware.com/midas3/folder/1550
