简要总结
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.

结局指标
主要结局
Stenosis index quantified [0-100%]
时间窗: 1 year
The stenosis index quantified subjectively by the physician, defined ration between cross-sectional area of the obstructed airway and that of a normal airway.
