Abstract
Optical coherence tomography is a noninvasive optical imaging modality that is rapidly gaining adoption in many clinical applications. OCT is capable of providing high-speed three-dimensional cross-sectional views into biological tissues with micrometer-scale resolutions. In this chapter, we will review the physical principles behind OCT starting early time-domain-based systems and then discuss the development of more recent high-speed Fourier-domain OCT systems. We will then discuss clinical utilization of OCT via two functional developments: Doppler-based OCT for the quantification of particulate flow rates such as blood flow and optical coherence elastography for mapping of tissue mechanical properties. Finally, we will discuss the development of endoscopic-based OCT for in vivo imaging within internal lumens such as the human airway.
