Micro- and macro-optical coherence tomography for revealing airway dynamics at multiple resolution scales
Optical coherence tomography (OCT) is an emerging, non-invasive, biomedical imaging modality that provides real-time micron-resolution imaging of tissue surfaces and subsurface tissue structures. In human airways, there are two length scales of interest. 1) On the centimeter scale, the airway lumen deforms during respiratory pressure cycling to reveal airway wall abnormalities and airflow bottlenecks. 2) On the micrometer scale, the airway epithelium is lined with cilia that beat to propel mucus, an important “muco-ciliary clearance (MCC)” mechanism that keeps our lungs healthy. In this presentation I will cover my lab’s development of several OCT-based imaging technologies to capture these airway processes, including endoscopic OCT, diffusion-sensitive OCT, and parallel line-field OCT. These technologies are designed to aid medical researchers in the diagnosis and treatment of upper airway obstructive disorders, and lung diseases including cystic fibrosis and COPD.
