OCT can function as a type of optical biopsy and is a powerful imaging technology for medical diagnostics because unlike conventional histopathology which requires removal of a tissue specimen and processing for microscopic examination, OCT can provide images of tissue in situ and in real time. Using OCT in combination with catheters and endoscopes enables high-resolution intraluminal imaging of organ systems. OCT can provide cross-sectional images of tissue structure on the micron scale in situ and in real time. OCT is analogous to ultrasound imaging, except that it uses light instead of sound. analysis of the retinal layers.Optical coherence tomography (OCT) is an emerging technology for performing high-resolution cross-sectional imaging.
