Comparing Human and Computer-based Quantification of Airway Stenosis From Bronchoscopic Images

Not Applicable

• Conditions: Airway Obstruction
• Interventions: Device: Computer-based Quantification of Airway Stenosis From Bronchoscopic Images.; Other: Human-based Quantification of Airway Stenosis

• Registration Number: NCT04846153
• Lead Sponsor: Brigham and Women's Hospital

Brief Summary

This is a pilot study to assess the utility of the automatic stenosis index quantification using 3D Slicer software (Computer-based Quantification). We will recruit three physicians to perform a similar analysis using video images of the same bronchoscopes images (Human-based Quantification). This study relates to the latter data collection.
