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.
