  • Medical Imaging
  • Surgical Navigation
  • Biomedical Engineering

Background:

  • Bronchoscopic navigation is crucial for minimally invasive procedures.
  • Accurate real-time tracking of bronchoscopes is essential for improved surgical outcomes.
  • Existing electromagnetic tracking (EMT) systems have limitations in accuracy and robustness.

Purpose of the Study:

  • To design and validate a novel prototype for bronchoscope tracking.
  • To enable accurate intra-operative alignment of pre- and intra-operative imaging data.
  • To augment surgical bronchoscopy with enhanced navigation capabilities.

Main Methods:

  • Construction of a novel mouth- or nose-piece bronchoscope model.
  • Direct measurement of bronchoscope movement outside the patient's body.
  • Fusion of movement data using a sequential Monte Carlo (SMC) sampler for robust alignment.

Main Results:

  • The prototype successfully measured bronchoscope movement data.
  • Accurate and robust intra-operative alignment between pre- and intra-operative images was achieved.
  • Validation on phantom datasets demonstrated the prototype's effectiveness.

Conclusions:

  • The developed bronchoscope tracking prototype shows promise for clinical application.
  • This novel approach offers an alternative to existing electromagnetic tracking systems.
  • The system enhances surgical bronchoscopy by providing superior navigation accuracy.
