Area of Science:

  • Biomedical Engineering
  • Respiratory Physiology
  • Medical Imaging

Background:

  • Limited understanding of lung movement in health and disease.
  • Current imaging methods (CT, MRI) have significant limitations for assessing dynamic lung motion.

Purpose of the Study:

  • To develop and evaluate a novel method for precise lung segment tracking during respiration.
  • To overcome limitations of existing techniques for studying respiratory movement.

Main Methods:

  • Balloon catheters fitted with electromagnetic sensors were placed in pig lung lobes.
  • Sensors tracked position at 40 Hz with sub-millimeter accuracy in an electromagnetic field.
  • Method evaluated across different body positions and tidal volumes.

Main Results:

  • The electromagnetic sensor method demonstrated ease of placement and no clinically relevant position drift.
  • Achieved sub-millimeter accuracy in tracking lung segment movements.
  • Measurements correlated with established knowledge, showing increased movement with higher ventilation volumes and positional differences in lung motion.

Conclusions:

  • This novel method provides high spatial and temporal resolution for tracking lung segment movements.
  • The reusable equipment is easy to implement as a research tool.
  • Applications include lung physiology research, navigated bronchoscopy, and radiation therapy.
