| Popis: | Optical coherence tomography (OCT) is a micron-scale imaging method, analogous to ultrasound measuring the backreflection of infrared light rather than sound. It can operate in 2D and 3D mode and exceeds the frame rate of video. The penetration depth of OCT is about 2 mm, depending on tissue types. Within this range, OCT has substantial advantages over other clinical imaging modalities such as ultrasound and MRI, particularly in resolution. In addition to structural imaging, OCT can assess birefringence (e.g., polarization-sensitive OCT for collagen), microflow (Doppler OCT), tensile properties (OCT elastography), and tissue chemistry (OCT spectroscopy). While OCT has demonstrated great potentials in many clinical applications, particularly cardiology, arthritis, and ophthalmology, this chapter will focus on introduction of its physical principles. |
