Area of Science:

  • Pulmonary Medicine
  • Medical Imaging
  • Biomechanical Engineering

Background:

  • Increasing prevalence of pulmonary diseases necessitates advanced non-invasive methods for assessing lung structure and function.
  • Current methods often lack comprehensive quantitative analysis of lung mechanics and disease-specific deviations.
  • Accurate assessment of lung anatomy and its mechanical properties is crucial for effective disease management.

Purpose of the Study:

  • To develop and validate a novel method for quantitative assessment of pulmonary structure and function.
  • To enable non-invasive evaluation of lung mechanics using clinical CT scans.
  • To provide intuitive 3D visualization and objective assessment for both normal and pathological lung conditions.

Main Methods:

  • Utilizing adaptive deformable surface models of the lung at end-inspiratory and end-expiratory volumes.
