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.
