Optical coherence tomography (OCT) enables imaging of tissue pathology in situ and in real time. Using ultrashort pulse lasers, ultrahigh resolutions of ∼1 μm as well as spectroscopic imaging are possible. OCT can function as a type of optical biopsy because it enables imaging tissue microstructure in situ without the need to excise and process a specimen as in conventional histopathology. OCT can be used to image pathology in tissues where biopsy is impossible.
