ABSTRACT

Optical coherence tomography (OCT) is a novel imaging modality capable of providing depth/time-resolved images of biological tissues noninvasively with micron-level resolution [1]. Since its invention in early 1990s, OCT has been viewed as an “optical analogy” of ultrasound sonogram (US) imaging, sharing many basic concepts of ultrasound such as the three fundamental imaging modes (A, B, and C scan), as illustrated in Figure 2.1.
