发帖数: 25265 | 2 Optical coherence tomography (OCT) is an optical signal acquisition and
processing method. It captures micrometer-resolution, three-dimensional
images from within optical scattering media (e.g., biological tissue).
Optical coherence tomography is an interferometric technique, typically
employing near-infrared light. The use of relatively long wavelength light
allows it to penetrate into the scattering medium. Confocal microscopy,
another similar technique, typically penetrates less deeply into the sample.
Depending on the properties of the light source (superluminescent diodes,
ultrashort pulsed lasers and supercontinuum lasers have been employed),
optical coherence tomography has achieved sub-micrometer resolution (with
very wide-spectrum sources emitting over a ~100 nm wavelength range).
Optical coherence tomography is one of a class of optical tomographic
techniques. A relatively recent implementation of optical coherence
tomography, frequency-domain optical coherence tomography, provides
advantages in signal-to-noise ratio, permitting faster signal acquisition.
Commercially available optical coherence tomography systems are employed in
diverse applications, including art conservation and diagnostic medicine,
notably in ophthalmology where it can be used to obtain detailed images from
within the retina. Recently it has also begun to be used in interventional
cardiology to help diagnose coronary artery disease[1]
