Area of Science:

  • Medical Imaging
  • Computational Biology
  • Cardiovascular Science

Background:

  • Accurate segmentation of the left ventricle myocardium is crucial for diagnosing and monitoring heart conditions.
  • Existing segmentation methods may struggle with complex anatomical variations and image noise.

Purpose of the Study:

  • To develop and validate a robust coupled level-set segmentation method for the left ventricle myocardium.
  • To incorporate a priori information and a novel stopping term for enhanced segmentation accuracy.

Main Methods:

  • A coupled level-set approach using fast marching initialization to evolve endocardial and epicardial fronts.
  • A novel stopping term combining gradient and region-based information.
  • Supervised segmentation using a coupling function and a probabilistic model trained on existing data.
