A Method of Providing Quantitative Information About the Lower Airways of a Lung
The present disclosure provides a method of providing quantitative information about a property of the lower airways of a lung using optical coherence tomography. The method comprises inserting a probe head of an anatomical optical coherence tomography device into the lower airways. Further, the method comprises directing light to, and receiving reflected light from, an internal wall portion of the lower airways. The light is suitable for optical coherence tomography. An electronic signal indicative of a phase difference between reference light and the received light is then generated. In addition the method comprises determining a quantity associated with a property of the lower airways by processing the generated electronic signal using a computer and computer software when the probe is positioned in the lower airways.
