Project Description

Objective

• Develop a semi-automatic segmentation algorithm for cardiac MR images of patients with congenital heart defects.
• Goal is to build a surface model showing the endocardial and epicardial boundaries, for surgical planning.
• Challenges:
  • Very large inter-subject variability due to heart defects
  • Intensity inhomogeneities within myocardium and blood pool
  • Similar intensity distributions within adjacent tissues (e.g. liver, chest muscle)

Approach, Plan

• Try existing open-source tools for segmentation and registration on the five datasets that we have so far.
• See where these methods fail, to focus our efforts for developing algorithms for segmenting hearts with congenital defects.
