Overview
OCT provides micron scale cross sectional images of tissue microstructure widely used in ophthalmology and intravascular imaging.
Technique
Interferometric detection of backscattered light yields high resolution images. Catheter or probe based delivery adapts OCT to different organs.
Clinical Uses
Retinal layer assessment in ophthalmology and coronary plaque microstructure in cardiology.
Limitations and Safety
Limited penetration depth and need for clear optical window. Specialized probes required.
