optical coherence tomography. Optical technique whereby computerized images are produced from photons reflected back from light passing through tissue, with each tissue creating a unique spectral signature. Present studies indicate accuracy is limited to depths of 4 mm, but represents a significant improvement in diagnostic capability over surface viewing as is presently obtained in standard endoscopies. Future studies may include the use of dyes and fluorescent markers for visualization and differentiation between benign and malignant tissues. Source: Reuters as reported by Stanford University.
Ocular Coherence Tomography. A diagnostic method which uses an optical device to generate a cross-section image of the retinal layers, allowing for measurement of tissue thickness.
Optical Coherence Tomography is a method of taking microscope images beneath the surface of living tissues such as skin. OCT uses light split into two paths in a configuration known as a Michelson interferometer. Light in one of the paths is used as a reference to effectively gate light that emerges from a very precise location in the sample.
