Optical Coherence Tomography (OCT)is a novel, non-invasive, high resolution special optical imaging techniques. In airway, Measure airway area and airway wall thickness is the most usage of Endobronchial Optical Coherence Tomography (EB-OCT). Recently, the new protocol of EB-OCT is used to measure airway compliance, We will establish a new methodology of EB-OCT for measuring airway compliance, which will provide a new means to study respiratory diseases.

Airway Compliance of different airway generation
Airway compliance is the property of the airway lumen area to change as pressure changes. This is caused by airway structure, the small airway without cartilage compared with medium and large airways, so the compliance would be different. But the methods of measuring airway compliance is difficult, In this research, we will use OCT to measure airway area (mm2), and record the airway pressure(cmH2O), The ratio of area change to pressure change is the compliance, we will measure and compare the compliance of different airway generation.

Airway Compliance of different people
Airway compliance is the property of the airway lumen area to change as pressure changes. This is caused by airway structure, the airway of COPD, asthma or pulmonary fibrosis compared to healthy people are different, so the compliance would be different. But the methods of measuring airway compliance is difficult, In this research, we will use OCT to measure airway area (mm2), and record the airway pressure(cmH2O), The ratio of area change to pressure change is the compliance, we will measure and compare the compliance of different people.
